✦ Synopsis

A number of crack propagation experiments are performed on sheets of a high strength steel. Momentaneous forces, crack lengths and velocities are measured. With this as input the dynamic stress-intensity factor is calculated with aid of a FEM program especially modified for the purpose. Observations regarding the dependence of crack propagation toughness on crack tip velocity and acceleration are made. A simple statistical analysis of the results is performed.

The paper discusses typical fracture mechanics problems which have been analyzed in order to evaluate the performance of the rotating crack model. The outcome indicates that the model is a promising tool for nonlinear analysis of concrete structures. For model-I cracking, the model is capable of sim

## Abstract Crack propagation in concrete structures is a very complicated process, and the distribution of cracks may significantly affect the behaviour of the structures under time‐dependent loading. If enough damage or extensive cracks exist in a structure, strengthening or repair using external
