✦ Synopsis

A procedure is developed for determining the stress intensity factors in cracked polygonal plates. The method uses eigenfunctions of angular regions and satisfies the boundary conditions exactly. Westergaard's stress functions are used to satisfy the boundary conditions at the crack. Numerical results are given. a half length of crack E elastic modulus u, L' radial and tangential displacements r, 0 polar coordinates lj = v/l + v NOTATION 1 root of transcendental equation v Poisson's ratio O. T normal and shear stress Z,(z) stress functions z=x+iy

Thermal shock stress intensity factor for an edge-cracked plate subjected to thermal shock is obtained from Bueckner's weight function method. It is shown that thermal shock stress intensity factor has maximum values with variation of time and crack length and that there is a critical crack length.
