with a constant. Saturation reduces the total absorption energy, dissipated energy, and elastic strain energy of rock samples. Key words: post-peak; saturation; strength property; damage mechanism; energy Cite... and plastic deformation of rock samples. Releasable strain energy Ue is stored in rock samples, which is mainly formed at the elastic deformation stage. After the axial load is removed, this part......

: Based on the compression mechanism for analyzing the cavity expansion problem in soil under high stresses, generalized non-linear failure criterion and large strain and energy conservation in plastic... dissipation analysis method, in which the energy generated from cavity expansion is absorbed by the volume change and shear strain caused in soil. The factors of large strain and dilatation were considered......
the first and the second laws of thermodynamics, and the load process is reversible, then the material possesses elastic property. It follows that there exists a strain energy function, UE=UE(εe, x, t... for the poly (methyl methacrylate) samples were carried out at different strain rates at ambient temperature. It is found that the elastic modulus of the material increases with increasing strain rate......
at crack tip causes rock burst to happen. Elastic energy attenuation degree and plastic energy change rate were defined. The results show that the maximum value is when strain of loaded coal-rock is , and rock burst happens when elastic energy attenuation degree surpasses the marginal value. The pulse number of electromagnetic radiation is directly proportional to plastic energy change rate......
