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 ...

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 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 ...
