Testing Equipment Universal Testing Machine (UTM)
Tension, Compression and Flexure Monotonic Static Tension Test
Single direction, Load increased slowly Crosshead Motion
Motor-driven Screw Hydraulically-driven Crosshead
Testing Methods Displacement Control
Open loop, Most Common Load Control
Close Loop Feedback, Expensive Strain Control
Close Loop Feedback, Expensive
Perform the Experiment Please be careful in Load Control The piston can move wildly at high
speeds if The specimen is not properly
mounted Specially tuned parameters are not
loaded
Computing Elastic ModulusSelect data points by clicking on any and then Right-click and choose “Add Trendline”
Computing Poisson’s RatioSelect Transverse Strain Line, and Right Click, and choose “Format Data Series”
