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.

Young's modulus is a crucial mechanical property in engineering, as it defines the stiffness of a material and tells us how much it will deform for an applied stress. In this video I take a detailed ...

Elastic Modulus The elastic modulus relates the applied stress to the strain it produces. In a material that obeys Hooke's Law, the initial uniaxial elastic response is linear with stress and strain ...

In this video I cover the interesting topic of true stress and true strain.

With a simple sample geometry, a 3-point-bend test can be used to obtain stress-strain behavior, elastic modulus in bending (flexural modulus), and failure limits in bending. The standards ASTM E855, ...
