An Elastic Interface Model for the Delamination of Bending-Extension Coupled Laminates
TL;DR: In this article, the authors considered the problem of an interfacial crack in a multi-directional laminated beam with possible bending-extension coupling and derived explicit expressions for the internal forces, strain measures, and generalized displacements in the sublaminates.

Yielding of steel sheets containing slits
TL;DR: In this article, a relation between extent of plastic yielding and external load applied was investigated, and panels containing internal and edge slits were loaded in tension and lengths of plastic zones were measured.
Analysis of crack formation and crack growth in concrete by means of fracture mechanics and finite elements
TL;DR: In this article, fracture mechanics is introduced into finite element analysis by means of a model where stresses are assumed to act across a crack as long as it is narrowly opened, which may be regarded as a way of expressing the energy adsorption in the energy balance approach.

The mathematical theory of equilibrium cracks in brittle fracture
TL;DR: In this paper, the authors present a unified view of the way basic problems in the theory of equilibrium cracks are formulated and discuss the results obtained thereby, and the object of the theory is the study of the equilibrium of solids in the presence of cracks.
