AIM AND CRITICAL OUTCOME

Why do it?


The aim of this module

Lay the foundation of material structure and properties relevant to material selection and manufacturing

Establish a broad and comprehensive understanding of

the many different failure modes that can occur, equipping you with the necessary tools to preventsuch failures


Bendable & transparentelectronics

Lighter & more fuel-efficientcars and airplanes

Longer-lastingbone and dental implants

Smart materials


The ultralight


StructureTiny hollow metallic tubes arranged into a micro-lattice

criss-crossing diagonal pattern with small open spaces between the tubes

10MTK 3A 11 Introduction & Course Outline

Worlds lightest material?

Ultralight Metallic Microlattices


Attributes100 times lighter than polystyrene

Low-density

Resilient



Applicationsthermal insulation

next-generation batteries

products that need to dampen sound and vibration



Nano technology


Additive manufacturing methods


3D Printing


Catastrophic failure


Make a structured, well-informed and

appropriate material selection to meet the design requirements when solving an engineering problem
