The Effect of Couple-Stresses on the Stress Concentration Around a Moving Crack

Abstract

The problem of a uniformly propagating finite crack in an infinite medium is solved within the linearized couple-stress theory. The self-equilibrated system of pressure is applied to the crack surfaces. The problem is reduced to dual integral equations and solved by a series-expansion method. The dynamic stress-intensity factor is computed numerically. © 1981, Hindawi Publishing Corporation. All rights reserved.
