With the rapid development of science and technology, multi-field coupling electro-magneto-elastic composite materials have been widely used in the manufacturing of advanced equipments and intelligent components. The safety of those composite materials which are under dynamic load has been a key issues

in the engineering. The project focus on the functionally graded electro-magneto-elastic composite materials, studies the dynamic fracture problem of multiple cracks. The main contents include: establish the fracture analysis model of multi-cracked functionally graded electro-magneto-elastic composite materials, and obtain the singular physical field near cracks for the four kinds of ideal electromagnetic condition along the crack surface, including two-dimensional and three-dimensional problems; analyze the interaction between multiple cracks; study the fracture criterion of those composite materials. The purpose of this project is to: obtain a comprehensive understanding of dynamic fracture behavior of those

materials with multiple cracks; reveal the relation among the crack and mechanism of interaction of multiple cracks; study the scope of application of the conventional fracture criterion, and establish a more comprehensive evaluation system. The successful implementation of the fund will enrich fracture mechanics theory, provide a scientific basis for the design of safety and the resistance to crack propagation.
