Paper Title:
Study on Stochastic Damage Constitutive Relation for HSHPC Material Subjected to Uniaxial Tension Stress
  Abstract

Based on the kind of damage constitutive models, such as spring friction block model and spring model, which are proposed for ordinary concrete by domestic and foreign scholars, and taking the differences which are caused by different failure mechanisms in mechanical properties of HSHPC and ordinary concrete into consideration, this paper presents the spring-friction block model which is suitable for revealing the stochastic damage constitutive relation of HSHPC material subjected to uniaxial tension stress. By introducing the failure strain stochastic field of concrete material subjected to uniaxial compressive stress, and according to the principle of energy conservation during the process of damage failure, the stochastic damage constitutive equation of HSHPC material subjected to uniaxial tension stress is derived. The theoretical results agree well with the experimental conclusions, and it shown that the proposed stochastic damage constitutive relation can objectively reflect the failure mechanism of HSHPC material. The research achievements will provide a basic research method for establishing the dynamic damage constitutive relation of HSHPC material.
