This video is an introduction to stress and strain, which are fundamental concepts that are used to describe how an object ...

Did you know that the typical stress-strain curve obtained from a uniaxial tensile test is just an approximation? It doesn't consider the fact that the dimensions of the test specimen change ...

The diagrams opposite show stress-strain curves for a linear elastic material such as a metal (top) and a non-linear elastic material such as rubber (bottom). If these materials are taken to some ...

It is determined as the value of the stress at which a line of the same slope as the initial portion (elastic region) of the curve that is offset by a strain of 0.2% or a value of 0.002 strain ...

in a material in the linear elastic region of a stress-strain curve. A high Young's modulus indicates a stiff material that resists deformation, while a low modulus characterizes a soft material that ...

The tensile behavior of composites is also different from that of metals in the 'plastic deformation' region of the stress/strain curve. The diagram shows the curve for a uniaxial sample tested along ...
