Abstract
A finite element (FE) modeling approach is developed for meso-scale hydraulic fracture in concrete. The FE models, consisting of aggregates, mortar and pores, are first generated by either random aggregate generation and packing or direct conversion of real micro-scale X-ray computed tomography images. The cohesive interface elements coupling fluid pressure freedoms are then inserted into the solid FE meshes by a developed Python code to simulate hydro-cracking. The developed approach was validated by simulating a few examples. It was found that the contents and distribution of aggregates and the fluid viscosity, the confining pressure ratios, the inclined angels of natural cracks and pores have significant effects on the hydraulic fracture resistance and the crack patterns.
