Micromechanical Investigation of Softening of Concrete Loaded in Compression
In this work softening of concrete specimens loaded in uniaxial compression is investigated by simulations with a micromechanical model. The simulation results are compared with experimental results. The micromechanical model calculates the mechanical response of the heterogeneous composite structure of concrete by simulating the crack-growth process. This is done by means of finite element analysis and fracture mechanics. Both distributed crack growth and localization into macrocracks are described by the model. The dependence of crack growth and softening response on the internal heterogeneous composite structure, the dimensions and the boundary conditions is shown.
