摘要
An accurate method which directly accounts for the interac ti ons between different microcracks is used for analyzing the elastic problem of m ultiple cracks solids. The effective elastic moduli for randomly oriented crack s and parallel cracks are evaluated for the representative volume element (RVE) with microcracks in infinite media. The numerical results are compared with thos e from various micromechanics models and experimental data. These results show t hat the present method is simple and provides a direct and efficient approach to dealing with elastic solids containing multiple cracks.
