Hybrid meshless/displacement discontinuity method for FGM Reissner's plate with cracks

• Advantages of the boundary element method and meshless approaches are inherited in hybrid MDDM to deal with crack problems. Cracked Reissner's plate non homogenous media is investigated by first time. High accurate/convergent solutions using Chebyshev polynomials can be obtained . Growing applications non-homogenous engineering structures require application powerful computational tools. A novel Meshless Displacement Discontinuity Method (MDDM) for cracked Functionally Graded Materials (FGMs) presented this paper. The fundamental slope deflection discontinuity an isotropic chosen as a part general create gaps between surfaces. governing equation satisfied methods such Local Petrov-Galerkin (MLPG) Point Collocation (PCM) Lagrange series interpolation mapping technique. Stress Intensity Factors (SIFs) evaluated analytically polynomials. accuracy verified comparison numerical analytical results.
