| Abstract: | In this paper,the hard inclusion is analyzed by using 3-D elastic-plastic finite element method.With the increasing of surrounding pressure step by steps,the fields of displacements,stress and the variation of elastic strain energy are obtained.The result and conclusions are valuable to study seismogenetic process,earthquake precursor and predictions. |
