For some viscoelastic polymers that are subjected to stress For some viscoelastic polymers that are subjected to stress relaxation tests, the stress decays with time according to where s(t) and s(0) represent the time-dependent and initial (i.e., time = 0) stresses, respectively, and t and t denote elapsed time and the relaxation time; t is […]
For some metal alloy, a true stress of 415MPa (60,175psi) For some metal alloy, a true stress of 415MPa (60,175psi) produces a plastic true strain of 0.475. How much will a specimen of this material elongate when a true stress of 325MPa (46,125psi) is applied if the original length is 300 mm (11.8 in.)? Assume […]
