中文摘要	Based on former meso-mechanics models, an efficient aggregates deposition method and an elements division criterion are developed in order to study the mechanical characteristic and the failure mechanism of concrete better. Based on the continuum mechanics, a reasonable meso-mechanics model of concrete and a parameters chosen method for meso-elements are presented which use the elastic damaged stress-strain relations to describe mechanical behaviors of the concrete. Numerical experiments with random distribution of aggregates for concrete samples for simulating Petersson's 3-point bending beam are then accomplished, from which the failure mechanism of concrete on meso scale is investigated. It is shown that the numerical mode is able to capture the complete process of concrete mode-I tensile fracture,which shows good agreement with corresponding experimental results.
