RANDOM PARTICLE MODEL FOR FRACTURE OF AGGREGATE OR FIBER COMPOSITES

A study is reported of the effect of the size of the specimen or structure on the maximum load, the subsequent softening behavior, and spread of the microcracking zone. The material is modeled as a system of randomly configured circular particles. The model is intended to simulate the behavior of concrete, but can also be used for the behavior of unidirectional reinforced fiber composites in the transverse plane, with microcracks parallel to the fibers and spreading in the transverse direction. Details of the study are described and the results are discussed. It was found that random generation of a particle system with a given size distribution can be accomplished quite easily, because the particles are circular (spherical) and are not in contact but are separated by contact layers whose thickness is unspecified, except for a given maximum thickness value.
