Stress concentration due to defects in a honeycomb structure
Dai-Heng Chen,Shingo Ozaki +1 more
TL;DR: In this article, the effect of defect size on tensile stress concentration was analyzed using the finite element method and the numerical results revealed that, in an elastic plate, it has an effect that is approximately equivalent to that of a crack with a length of (n + 0.3)w, where n is the number of defect cells and w the cell width.

On the stress singularities in the plane elasticity of the composite wedge
John P. Dempsey,G. B. Sinclair +1 more
TL;DR: In this paper, a composite, two-dimensional, linear elastic wedge for singular stresses at its vertex is examined and a full range of wedge boundary and matching conditions is considered, using separation of variables on the Airy stress function.

Debonding and crack kinking in foam core sandwich beams—II. Experimental investigation
Srinivas Prasad,Leif A. Carlsson +1 more
TL;DR: In this article, debonding and crack kinking in sandwich beams was experimentally examined, and also analyzed using the finite element method, and it was found that the Young modulus of the core has a profound effect on the tendency of the facing/core interfacial crack to deflect (kink) into the core in DCB testing.
