摘要：

Based on the concept of the energy-momentum tensor, the paper derives the conservation laws relevant to free energy and complementary free energy of electro-magneto-elastic media. From those laws, the path-independent integrals are presented. Other laws and associated integrals are also introduced. Some integrals are evaluated to obtain the energy release rate for the mode III electro-magneto-elastic fracture problem.
