Numerical analysis of dynamic compressive properties of basalt fiber engineered cementitious composites after elevated temperature
Abstract The basalt fiber engineered cementitious composites (BF-ECC) was a superior cementitous material when used for tension loading. And it can prevent the development of wide cracks. In this paper, the dynamic compressive mechanics of BF-ECC after elevated temperature exposure(100 °C, 200 °C, 400 °C and 600 °C) is investigated. Parameter analyses are conducted to investigate the effect of the temperature and strain rate. In addition, a dynamic constitutive model including the damage factor function and the temperature effect function is constructed. It is extended and applied to the rate-type constitutive relation of BF-ECC materials after elevated temperature, and the numerical analysis results are compared with the experimental results to verify the applicability of the model.
Highlights The dynamic compressive properties of BF-ECC after elevated temperature are researched. Parameter analyses are conducted to investigate the effect of the temperature and strain rate. The improvements are made to the components of the Z-W-T constitutive model, and a dynamic constitutive model including damage factor function and temperature influence function is constructed.
