TLDR
In this article, the elasticity problem for an orthotropic strip or a beam with an internal or an edge crack under general loading conditions is considered and numerical results are given for four basic loading conditions, namely, uniform tension, pure bending, three point bending, and concentrated surface shear loading.Abstract:
The elasticity problem for an orthotropic strip or a beam with an internal or an edge crack under general loading conditions is considered. The numerical results are given for four basic loading conditions, namely, uniform tension, pure bending, three point bending, and concentrated surface shear loading. For the strip with an edge crack additional results regarding the crack opening displacements are obtained by using the plastic strip model. A critical quantity which is tabulated is the maximum compressive stress in the plane of the crack. It is shown that this stress may easily exceed the yield limit in compression and hence may severely limit the range of application of the plasticity results.read more

Universal features of weight functions for cracks in mode I
Grzegorz Glinka,G. Shen +1 more
TL;DR: In this paper, a universal weight function expression with suitable reference stress intensity factors was used to derive the weight functions for internal and external radial cracks in a thick cylinder, and these weight functions were then further used to calculate the stress intensity factor for radial cracks.

Fracture toughness and R-curve behavior of laminated brittle-matrix composites
TL;DR: In this article, the fracture toughness and resistance-curve behavior of relatively coarse-scale, Niobium/niobium aluminide (Nb/Nb3Al) laminated composites have been examined and compared to other composites with (in situ) Nb particulate or microlaminate reinforcements.
