`` Problems of crack, near the edge of box shell ''
＜研究発表要旨＞
We consider the state of stress in a box shell formed by two semi-infinite
plates jointed at right angle. The box shell is weakened by a crack coming
out into the edge. Using a generalized integral transforms method, the
problem is reduced to a singular integral equation over a finite interval
with the kernel of Mellin convolution type . An exacted solution has been
obtained in quadratures by reducing the original problem to the Riemannian
problem. Asymptotics of the obtained solution in the intersection point of
the crack and the edge of a box is investigated. Numerical results for the
stress intensity factors in the apex of crack are given.
