Uniform stress field inside a non-parabolic open inhomogeneity interacting with a mode III crack
Archives of Mechanics, 2021 Using conformal mapping techniques, analytic continuation and the theory of Cauchy singular integral equations, we prove that a non-parabolic open inhomogeneity embedded in an elastic matrix subjected to a uniform remote anti-plane stress nevertheless ...
