3D INTERFACE CRACK IN FULLY COUPLED ELECTROMAGNETOTH ERMOELASTIC MULTIPHASE ANISOTROPIC COMPOSITES. PART Ⅰ: BASIC THEORY AND MATHEMATICAL MODELING
This two-part contribution presents a new theory with hypersingular intergro-differential equation method to analyze 3D interface crack in fully coupled electro-magneto-thermo-elastic multiphase anisotropic composites under extended electromagnetothermoelastic coupled loads through intricate theoretical analysis and numerical simulations.Part Ⅰ is devoted to the basic theory and mathematical modeling,and part Ⅱ discusses numerical simulation method and its application.In this part,3D interface crack is reduced to solving a set of HIDEs.The behavior of extended displacement discontinuities around interface crack front terminating at interface is analyzed.Analytical solutions for extended singular stresses,ESIFs (ESEFs) and extended energy release rate are provided.
