The trusted ANSYS mechanical suite rapidlysolves complex structural problems with ease.

Confdently predict and optimize how your product

will behave with ANSYS advanced physics.

Predictability is Paramount

Computing the response of a structural systeminvolves analyzing a wide range of physics:stresses, deformations, vibration characteristics,reaction forces and residual strains. To get anaccurate answer, simulation must take into

account all interactions between the variousparts of a product, its working environment(such as thermal conditions), and the eects ofother forces such as electromagnetics and uiddynamics. And capturing materials is critical. Allof this complexity must be handled eciently byadvanced solver techniques that reliably captureall subtleties, such as material properties changes,contacts status and erosion of parts.

Structural mechanics solutions from ANSYS set theindustry standard in engineering, providing youand your team with the ability to simulate every

structural aspect of a product using linear andnonlinear static analyses or mechanisms analysis.Our products incorporate extensive dynamicsolution capabilities, including modal analysis forcalculating natural frequencies and mode shapes,harmonic analysis for determining harmonicallytime-varying load response, linear and nonlineartransient dynamic analysis, and spectrum analysisfor random vibrations.

Using the ANSYS end-to-end solution, you canmodel any type of geometry, from slender andthin structures to massive parts, using the latestgenerations of beams, shells and solid niteelements formulations. Nonlinear geometriceects assist in performing large deformationsor nonlinear stability analyses.

Characterizing material behavior is intuitivethrough use of our vast library of mathematicalmaterial models, no matter what your structure ismade of including composites.

Because complex systems are made of multipleparts, ANSYS tools enable you to capture thecritical interactions between parts. Whetherusing contacts, special connections (includingsprings, dampers and spotwelds) or joints deningthe kinematic relationship between bodies, oursolutions lead to insight into the most complex

interactions.

Use of ANSYS compositematerial models canlead to lightweight andstrong products. Oursolutions dene layeredcomposites and help yourR&D team to understand

potential failure.

Productivity: In-Depth Understandingin the Shortest Possible Time

Without the right tools, simulating your mostcomplex products can be beyond challenging.After all, structural engineers should focus moreon the physics of the model than on the underlyingmathematics. The mechanical simulation inter-face based on the ANSYS Workbench platformenables users to model all applications, fromvery simple to very complex. The interface cantake weeks out of a CAE process by eliminating

manual le transfer, results translation andre-analysis time.

Within this highly productive environment, youcan take advantage of a wide range of veryadvanced technologies. For example, the bidirec-tional link to all major CAD systems removes theneed for model repair and provides automatedmodel updates upon design changes.

Performance to Solve Large Models Faster

Current trends in simulation show the use ofincreasingly larger models, no matter the industry.Our structural solution incorporates parallel algo-rithms for a faster computation time: The entiresolution phase runs in parallel, including stiness

matrix generation, linear equation solving andresults calculations in both shared and distributedmemory processing.

We also oer unique solutions based on GPUboard utilization. The combination of parallelcomputing and performance via GPU can furtherspeed up your simulations.

Additional advanced techniques such as compo-nent mode synthesis (CMS), submodeling methodsand proprietary acceleration techniques cancontribute to eciently handling large models.

All these techniques allow you to increase thenumber of design variations you can compute ina given period, therefore leading to better, moreoptimized products. The end result of an ANSYSsimulation is condence that your product willthrive in the real world.

The ANSYS smoothing algorithms and control tools allow us

to ensure the quality of the interpolated data as well as the

robustness of the mapping procedure. Ultimately, this saves

time in setting up our simulation models.

ANSYS state-of-the-art technology empowers you to simulate

every aspect of your product, from straightforward to complex.

Robust Nonlinear Analysis

The Right Material Model

To understand and accurately characterizematerial behavior, ANSYS provides a vastlibrary of mathematical material models thataid in simulating materials. You can apply these

constitutive models to metal, rubber, plastic,glass, foam, concrete, biotissue and specialalloys. ANSYS structural tools include modelcapabilities for moisture diusion as well asinitial strain and stress states.

Interaction between Parts

Our robust, complete set of contact capabilitiesincludes surfacesurface, linesurface and lineline contact for exible and rigid bodies. Contactbehavior can account for constant or orthotropicfriction as well as sliding behavior; these areapplicable for structural, thermal and multi-

disciplinary contact applications. Fast, automaticcontact detection backed by powerful algorithmsleads to fast and accurate solving of modelsinvolving contacts.

Robust Solvers for Complex Problems

ANSYS structural mechanics solutions oer alarge library of out-of-the box equation solvers.The compilation contains the sparse direct solver,preconditioned conjugate gradient (PCG) iterativesolver, Jacobi conjugate gradient (JCG) solutionand others.

You can be condent of a robust solution, sinceANSYS uses default settings for both elementsand solver. You can override the default options;however, our many years of ne-tuning haveresulted in an ecient solution to your mostcomplex problems without having to manuallyset required controls and options.

Creating Your Own Elements or Materials

Very advanced applications and researchactivities require user-dened materials or a newelement formation. With ANSYS tools, you can

extend native capabilities through user elements,user materials or user routines to create your ownmodels, such as friction.

Assemblies requiremodeling contact betweenparts as well as specicinterfaces, such as gaskets

We use ANSYS tools to calculate stress, stiness, deformation and natural

frequencies of critical vehicle components and subsystems. An important

capability is advanced analysis of a variety of nonlinear materials.

Advanced Solutions

Rigid and Flexible Bodies

Mechanical systems can contain complexassemblies of interconnected parts undergoing

large overall motion, such as in groundvehicle suspension assemblies,

robotic manipulators inmanufacturing processes,

and aircraft landing gearsystems. For a faster,

more ecient solutionto this problem class,

ANSYS provides arigid multibodydynamics module.With minimalinvestment inmodel setup andcomputational

resources earlyin development,you gain deep

understandingof motion and

stability of

mechanical systems. Then, if more delity isrequired with detailed designs, you can easilyconvert the model to a partially or fully exiblerepresentation, one capable of capturing largedeformations and material nonlinearities.

Rotating Structure Dynamics

Rotordynamics applications serve to identifybehavior and diagnosis of rotating structures. Thecapability is commonly used to analyze behaviorof structures ranging from jet engines and steamturbines to auto engines and computer diskstorage. Rotordynamics can eectively computecritical speeds and the eect of unbalanced loadson a structure.

ANSYS solutions provide modal and transientanalysis capabilities. They allow creation ofCampbell plots to identify critical speeds ofsingle or multiple spool systems, for beams,

shells and solid elements. Bearings models areavailable; an interface enables importing bearingcharacteristics from outside sources. For static,modal or harmonic analysis of rotating parts withgeometric patterns, cyclic symmetry modelingreduces computation time.

We use ANSYS as a virtual laboratory, since ANSYS code

is really close to the actual physics. It assures you when

something is a good idea and demonstrates clearly when

a design fails.

Using ANSYS technology, you can analyzesquealing via complex eigensolvers to identifyunstable modes. Three dierent methods providevarious levels of accuracy and computation

speed by including various levels of pre-stresson the model.

Campbell diagrams identify critical speed of rotatingstructures over a range of variations of a systemsrotational velocity.

Beyond Standard Applications

Combining Other PhysicsTo accurately model a product, you must con-sider its environment. For example, will the

product experience thermal loads thataect the structure? Will it be part of a

system controlled by electric orpiezo-electric components?

ANSYS tools enable you tocompute thermalstructural,

thermalelectric, piezo-electric andacoustics impacts. Strong couplings use

coupled elements that carry all necessarydegrees of freedom.

Easy Data ExchangeIn some product analyses, weak coupling isappropriate; this can entail transferring data

from one simulation to another. Mapping databetween physics is a painful process withoutthe right tools.

The ANSYS Workbench platform allows a seam-less data transfer from one physics area toanother, and it automates the mapping betweendissimilar meshes. Workbench easily importsdata from external sources, such as point clouds,and maps them onto your current structure.You can modify scaling, units and orientations
