An Experiment-Based Cumulative Damage Mechanics Model of Steel under Cyclic Loading

An Experiment-Based Cumulative Damage Mechanics Model of Steel under Cyclic Loading Based on the stress-strain hysteretic curves obtained from the tests on steel under cyclic loading, a cumulative damage mechanics model using plastic strain as a basic variable is proposed in the paper, in which the effects of damage on the modulus of elasticity and the yielding stress of steel are taken into consideration. The material parameters of the model are determined according to the experimental hysteretic curves. Comparison of the theoretical hysteretic curves and repeated tensile stress-strain curves obtained from the suggested cumulative damage mechanics model with those from the tests shows that the model suggested in this paper agrees very well with the tested results. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Advances in Structural Engineering SAGE

Abstract

Based on the stress-strain hysteretic curves obtained from the tests on steel under cyclic loading, a cumulative damage mechanics model using plastic strain as a basic variable is proposed in the paper, in which the effects of damage on the modulus of elasticity and the yielding stress of steel are taken into consideration. The material parameters of the model are determined according to the experimental hysteretic curves. Comparison of the theoretical hysteretic curves and repeated tensile stress-strain curves obtained from the suggested cumulative damage mechanics model with those from the tests shows that the model suggested in this paper agrees very well with the tested results.
