Abstract

We develop an analysis method, which is named "global-local finite cover method (global-local FCM)", for the analysis of local crack growth in overall structure, and apply it to numerical simulations of propagating cracks in concrete due to reinforcement corrosion. First, we formulate the global-local FCM in conjunction with the hierarchical mesh for a kind of multi-scale analysis of RC structure. Secondly, numerical implementations for the FCM analysis of multiple cohesive crack growth are explained. Thirdly, the performance of global-local FCM is assessed for the approximation of mechanical behavior of hierarchical heterogeneity including local crack propagations. Finally, we apply the proposed method to global-local numerical simulations of propagating cracks in RC structure due to reinforcement corrosion.
