This work presents extended hypersingular integral equation (E-HIE) method to analyze the multiple 3D mixed-mode flaws problem in fully coupled electro-magneto-thermo-elastic multiphase composites under extended electro-magneto-thermo-elastic coupled loads through intricate theoretical analysis and numerical simulations. First, the problem is reduced to solving a set of E-HIEs. Analytical solutions for the extended singular stresses, the extended stress intensity factors (E-SIFs), the extended energy release rate and the extended strain energy density factors (E-SEDFs) near the flaws front are obtained. Then, the numerical method for the E-HIEs for two 3D flaws subjected to extended coupled loads is proposed. Finally, numerical solutions of E-SIFs and E-SEDFs of some examples are given, and the effect of flaws orientation, interaction and shielding is discussed.
