О разрушении материала с периодической системой соосных круговых трещин при действии направленных вдоль них начальных напряжений
В.Л. Богданов
Abstract
An axisymmetric problem on the interaction of a periodic system of coaxial
cracks in an infinite material is investigated by the use of approaches of
the linearized mechanics of solids. Two non-classical mechanisms of fracture
are considered, namely, fracture of solids with initial stresses acting
parallel to the cracks' planes and fracture of materials under compression
along cracks. Numerical results are obtained for a highly elastic material
with the Bartenev–Khazanovich elastic potential. The dependence of the
parameters of fracture on the loading conditions, physico-mechanical
characteristics of materials, and geometric parameters of the problem is analyzed.
