Abstract

A newly developed crack growth model, Nielsen (1990), based on an energy balance criterion is presented in the paper. The model leads to a first order differential equation which can predict crack propagation mode I, and determine the strength and deformations for any condition. The model has recently been used to predict crack growth metals subjected to dynamic loading, Hansen (1994a). In this paper the model is compared with three point bending tests on plain concrete beams, where parameters have been beam dimensions, the strength and aggregate size.
