A 3D FEM Mesoscale Numerical Analysis of Concrete Tensile Strength Behaviour

A three-dimensional (3D) finite element method (FEM) based on an inserted cohesive numerical analysis procedure was developed for concrete mesoscale systems the ABAQUS platform with python scripts. Aggregates were generated dividing existing geometrical algorithms to randomize arbitrary spheres. Simultaneously, randomizations of maximum aggregate size and uniform distributions particles also considered. An FEM mortar phase in along interfacial transition zone (ITZ) by inserting a element. Numerical parameter analyses performed nine different varying coarse volume fraction (α) ITZ tension strength (ITZ-S). The mechanical performance coupling effects α ITZ-S evaluated simulated tensile loading. results simulations properties, such as strengths damage behaviour systems, verified experimental results. proposed generation approach simulation can be used researchers better understand how affect systems.
