Solution of two-parameter cohesive law using Chebyshev polynomials for singular integral equation

摘要: Abstract Complex stress and displacement potentials are used to examine the effect of cohesive on crack opening around a two-dimensional slit-like in an isotropic material. A two-parameter right-angled triangular relationship between is assumed hold. Following earlier work, problem reduced singular integral equation (SIE), which solved numerically using Chebyshev polynomials. The results quantify that has opening, field crack. Finally, it also shown region action (“cohesive zone”) comes out as part solution based choice two parameters. presented method more direct than commonly variational methods.
