On the application of representative volume elements for steel fiber reinforced high performance concrete ‐ a numerical study

In this contribution, ellipsoidal and hexagonal prism representative volume element (RVE) which characterize the steel fiber reinforced high performance concrete (HPC) along a preferred fiber direction are constructed and analyzed numerically. A virtual experiment is simulated using a microscopic boundary value problem based on two different RVEs. The suitable mechanical and periodic boundary conditions are applied on each RVE at the microscale. The homogenized macroscopic quantities are computed using their microscopic counterparts. The microscopic response of ellipsoidal and hexagonal prism RVE are simulated and the macroscopic behavior of steel fiber reinforced HPC is analyzed.
