Resumen:
Engineering components may be subjected to complex loading in tension, compression, bending, torsion, or pressure, or combinations of these. If sufficiently severe, such combined stresses can act together to cause the material to yield or fracture. Predicting the safety limits of a material under combined stresses requires the application of a failure criterion. The yield behavior of polymer solids, unlike most metals, depends upon the mean normal stress as well as the deviatoric components of the applied state of stress (Quinson, 1996). This means that deformation behavior in polymers is very sensitive to hydrostatic pressure (Caddell, 1974)Yield criteria modified to account for the effect of hydrostatic pressure ? Modified Von Mises and Modified Tresca- are usually employed to describe yielding behaviour of polymers.
