In engineering, it is common to use terms associated with the human experience to describe characteristics of materials—stress, strain, strength, fatigue and toughness. (Courtesy of Gary T. Fry.) ...
Shear stress-strain curve (left) and corresponding viscosity-stress curve (right) for materials with and without a yield stress. In this test, the stress ramp rate can be an important factor since ...

An Introduction to Stress and Strain

This video is an introduction to stress and strain, which are fundamental concepts that are used to describe how an object ...
Engineers have long used stress-strain curves to uncover a host of material properties. The curves are created by plotting the results of tensile strength tests of material samples, putting stress ...
The entire stress-strain curve can now be determined using nanoindentation with a flat-ended cylindrical punch and novel analysis of the resulting force-displacement data 1. Unlike pyramidal indenters ...
Stress-strain curves estimated from properties measured by instrumented indentation at 500mN. The simulated force-displacement curves are plotted in Figure 5, together with typical experimental ...
The deformation in the neck region is unstable as the true stress continues to increase as the area decreases. This region of the tensile stress/strain curve can only be realized under constant strain ...
Nominal stress/strain curves for Al 2 O 3 (a), a low carbon steel (b), a cross-linked natural rubber (c), and a the polymer, polymethyl-methacrylate, tested at 122 C are shown inthe figure opposite.
