Some materials have a non-linear relationship between stress and strain, a behavior exhibited by materials such as a rubber. These are nonlinear elastic materials for which the slope of the ...

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

The top diagram shows a tensile stress-strain curve for a 6,6 Nylon. It should be noted that the strain at fracture is very large (300%) compared to that for metals. The lower diagram shows the ...

The hypothesis used in developing the stress and strain in the shaft is that all points on a cross-section of the shaft experience the same angle of twist. The angle of twist for a section of length L ...
