Numerical study of shrinkage and heating induced cracking in concrete materials and influence of inclusion stiffness with Peridynamics method

This paper is devoted to numerical modelling of cracking in concrete-like materials by explicitly taking into account microscopic heterogeneities. A method based on peridynamics theory proposed. The formulation and implementation the are first presented. Its efficiency initiation propagation multiple cracks heterogeneous then demonstrated. proposed further applied description process induced drying shrinkage temperature change concrete composites containing different types inclusions. emphasis put effect inclusion stiffness patterns. series simulations performed. Comparisons between results experimental observations
