Abstract: | An accurate method which directly accounts for the interactions between different microcracks is used for analyzing the elastic
problem of multiple cracks solids. The effective elastic moduli for randomly oriented cracks and parallel cracks are evaluated
for the representative volume element (RVE) with microcracks in infinite media. The numerical results are compared with those
from various micromechanics models and experimental data. These results show that the present method is simple and provides
a direct and efficient approach to dealing with elastic solids containing multiple cracks.
