| Research Abstract |
Conducting numerical experiments to simulate accurately as much as possible the growing process of fine-scale cracks to larger ones and the collapse phenomena of partially failed brocks in heterogeneous meso- and micro-scale structures of concrete, we re-considered the effects of heterogeneities on the development mechanism of “structural strength" of concrete specimens and presented the evaluation method of actual concrete's “material strength".
