Node projection strategy for FEM simulating cross-scale crack propagation in massive concrete structures
Engineering Structures（2023）
Abstract
•A novel simulation method for massive concrete structures with cracks is proposed.•Refined simulation model with irregular cracks is established based on the method.•The method reduces meshing difficulty in complex 3D models with cross-scale cracks.•Crack propagation during dam construction and under an earthquake is examined.
