2D analysis of functionally graded magneto-electro-elastic composite materials with cracks under SH waves
Functionally graded materials are composite materials with continuously variable material properties. They possess huge potential for applications in modern industry, because of their enhanced qualities: thermal barrier effects, protection from corrosion and oxidation, improved toughness and stress. In our research we consider functionally graded magneto-electro-elastic materials with cracks, subjected to anti-plane wave and evaluate stress concentration near the crack tips in this type of materials with respect to external loading for different material grading. Boundary integral equation method (BIEM) is used for the numerical solution. Numerical examples are presented to show the dependence between the stress intensity factors and the frequency of the applied dynamic load.
