Discrete Model for Concrete Fracture: Numerical Study of Dynamic Response

Discrete Model for Concrete Fracture: Numerical Study of Dynamic Response Abstract The contribution presents simulations on concrete specimens.

Abstract

Abstract The contribution presents simulations on concrete specimens. The discrete meso-scale particle model with random geometry based on Voronoi tessellation is used. The model was enhanced with dynamic solver based on implicit Newmark method. Model is tested on cantilever beam loaded by a force at the free end to verify the ability of the model to simulate the dynamic behavior of a simple linear elastic material. Results computed with different time discretization and model settings are compared. The behavior of the model in nonlinear regime is investigated on concrete specimens loaded at different displacement rates. The constitutive law used within this contribution is insensitive to strain rate.
