Abstract

The paper presents a next stage in the development of excitable cellular automata method which allows one to model energy flow propagation in a loaded solid under external mechanical and thermal-dynamic loads. At this stage the method is proposed for assessing the probability of crack initiation near geometric stress concentrators. Patterns of various mechanical characteristics distribution on the specimen surfaces are given, as well as the time dependence graphs of the average values of these parameters in the vicinity of notch tip. Some aspects of the notch shape effect over the deformation patterns as well as prospects of the proposed approach development are discussed.
