The tubular interface crack in a hollow composite cylinder under static torsion with four frequently encountered constraint edges

다국어 초록 (Multilingual Abstract)

A tubular interface crack in a hollow composite cylinder is analyzed under static torsion. For four frequently encountered constraintedges--free-free, clamped-clamped, free-clamped, or clamped-free edges--theoretical derivation is performed by the Fourier integraltransform method. The mixed boundary value problem associated with a mode-III interface crack for each case is reduced to a singularintegral equation, from which the numerical results of Stress intensity factors (SIFs) are obtained by the Lobatto-Chebyshev quadraturetechnique. Numerical results of SIFs show that a coupled effect exists of geometrical and physical parameters on the interfacial fracturebehavior, which clearly relates to the selecting of constraint edges.
