Simulations of Dynamic Concrete Fracture with Brazilian Splitting Test
Original language description
Concrete fracture is a phenomenon that material science deals with since its very beginning. With increase of computational capacity, linear models previously used for the description of material behavior in the vicinity of stress concentrators are being replaced with complex models using nonlinear material laws. Such models can be continuous, but for the better description of material behavior at the scale, where heterogeneities are recognized, discrete formulations are usually adopted. The contribution presents simulations of concrete fracture in dynamic regime using rigid body spring network. The material is represented by interconnected rigid cells of convex polyhedral shape. In the dynamic regime, for relatively slow loading rates, use of implicit time integration scheme for solving system of equations is quite common. For faster loading rates, the explicit scheme is usually used, however, in the presented contribution, the implicit scheme is conveniently used as well. The time step length is then not restricted by the stability of the system, but only by the desired accuracy. Model is applied to dynamic simulations of Brazilian splitting discs experimentally investigated in literature.
