Engineers have long used stress-strain curves to uncover a host of material properties including elastic limit, elastic and plastic ranges, yield point, ultimate and rupture strengths, and the ...

This class discusses how shear, compression, and tensile stress impact a material's properties, how force is shown on a stress-strain graph, and common methods manufacturers use to test a material's ...

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 ...

Because of their very large molecular weight (~ 10 6) polymers behave differently from the low molecular weight metals during plastic deformation leading to a ductile fracture.The top diagram shows a ...

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, ...

Figure 3: Stress–strain curves at 1,650 °C. ε̇ 0 is the initial strain rate. We note that the undulated feature after yielding, particularly at ε̇ 0 = 1 s -1 , is typical of dynamic ...
