3D mesoscale fracture analysis of concrete under complex loading

Analyzing mechanical behavior at the mesoscale level should be a powerful tool for higher heterogeneous materials like concrete. In this study, the mechanical and damage analysis of concrete were investigated using a 3D mesoscale model under complex loading. A less time-consuming method was proposed for constructing the realistic mesostructure of concrete. The finite element simulation showed good agreements with the uniaxial and biaxial...
