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 ...

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 ...

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 ...

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, ...
