| description | The SAP (Super Absorbent Polymers) concrete is a new kind of concrete materials with uniformly distributed spherical pores with diameter of millimetre-size. The study on propagation characteristics of SAP concrete is important to give a full comprehending of its dynamic mechanical properties.Based on the ABAQUS platform, the numerical model to simulate the propagation of stress wave in SAP concrete was established by introducing the function of dynamic compressive strength increment DIF-fc,r caused by strain-rate effect of the material itself and strain rate into the expanded Drucker-Prager model. Totally six kinds of triangle stress wave have been investigated, and the transmitted stress wave for each triangle incident stress wave through different pressure bars has been analysed. Based on the numerical calculation, the laws of attenuation and dispersion effect on stress waves in the SAP concrete with evenly distributed millimetre-size spherical pores inside have been analysed. |
