Abstract: Tests have been conducted to determine the effect of tensile-mean-strain on cyclic properties, low cycle fatigue, and total absorbed plastic strain energy to failure of ASTM A-516 Grade 70 ...

Abstract: The dynamic response of a simple beam excited at its midspan by the action of a turbomachine secured to it, is investigated in detail. The forcing function includes transients at startup or ...

Abstract: The aim of this investigation was to develop a method for the prediction of the high-strain multiaxial fatigue life (low-cycle fatigue) of a steel, based on high-strain uniaxial fatigue data. ...

Abstract: Results of an experimental investigation of a constant-amplitude, fully reversed biaxial tension-compression out-of-phase cyclic loading are presented first. An energy-based fatigue theory is extended ...

Abstract: Constant strain-rate plastic straining followed by creep tests were conducted to investigate the effect of prior plastic straining on the subsequent creep behavior of 304 stainless steel at room ...

Abstract: In this part, a constitutive model for creep deformation is presented, which includes the effect of prior plastic straining. The model is capable of predicting the influence of plastic or creep ...

Abstract: A multiaxial fatigue failure criterion is proposed based on the strain energy density damage law. The proposed criterion is hydrostatic pressure sensitive; includes the effect of the mean stress, ...

Abstract: In this part a rate-dependent elastic-plastic constitutive model is presented which is an extension of our earlier rate-indpendent model. The effect of prior creep on the subsequent inelastic ...

Abstract: The transient vibration of a beam supporting an unbalanced rotor is investigated using finite element discretization techniques. The rotor speed is time dependent to simulate transients at startup. ...
