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 ...

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 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 ...
