A Nonlinear Effect in Mode II Crack Problems.

Abstract

A recent result of Stephenson shows that, when finite deformations are taken into account, a crack under Mode II loading conditions in plane strain will open, at least near the crack-tip and at least for certain elastic materials. In this note, the matter is investigated further, and it is shown that, in general, nonlinear effects - even at small loads - lead either to crack-opening or apparent interpenetration of the crack-faces when the loading is of Mode II-type.
