Abstract: Experiments are reported for fatigue tests in bending and in torsion at hardness levels from fully annealed to fully hard and super quenched. Results indicate a linear relation between fatigue ...

Abstract: It is shown that a creep surface, defined in terms of a prescribed creep rate, can be determined from the multiple integral formulation representing the creep data. The creep surface for 304 ...

Abstract: Kernel functions for mixed-time parameters in the multiple integral representation of the nonlinear viscoelastic behavior of polyvinyl chloride were determined from both two-step tension and two-step ...

Abstract: It is shown that defining an incompressible material as one whose response to stressing or straining is insensitive to volumetric-type changes in strain or stress allows the derivation of ...

Abstract: Nonlinear constitutive equations are developed and used to predict from constant stress data the creep behavior of 2618 Aluminum at 200°C (392°F) for tension or torsion stresses under ...

Abstract: Creep and creep recovery data of 304 stainless steel are reported for experiments at low stress levels under combined tension and torsion at 593°C (1100°F). The data were represented ...

Abstract: Creep and creep-recovery data of 304 stainless steel are reported for experiments under constant combined tension and torsion at 593°C (1100°F). The data were represented by a ...

Abstract: Combined tension and torsion creep experiments are reported in which (A) one stress component was increased or decreased while the other remained constant; (B) one stress component was removed ...

Abstract: Experimental results are presented for fatigue of closed-ended thick-walled tubes of 2.5 wall ratio and 32.3 mm (1.27 in.) ID for SAE 4333 steel subjected to pulsating internal pressure. Results ...
