Semi-analytical representation of stress singularities as occurring in cracks in anisotropic multi-materials with the scaled boundary finite-element method
Chongmin Song,John P. Wolf +1 more
TL;DR: The scaled boundary finite element (SDFE) method as discussed by the authors is a semi-analytical boundary-element method based on finite elements, which is applied to fracture mechanics problems, but only the actual boundary of the body, but not the straight crack faces and material interfaces passing through the crack tip, is spatially discretized with finite elements.

Free-Edge Effects in Composite Laminates
TL;DR: A survey on relevant literature from more than three decades of scientific research on free-edge effects is given, which deals with approximate closed-form analyses, as well as numerical investigations by the finite element method, the finite difference method, and several other numerical techniques.

Interlaminar Stress Concentrations in Layered Structures: Part I - A Selective Literature Survey on the Free-Edge Effect since 1967
TL;DR: In this paper, the authors present a simple closed-form method for the analysis of the stress fields in the vicinity of free laminate corners with arbitrary layup, based on adequate stress shape assumption.

Evaluation of power-logarithmic singularities,T-stresses and higher order terms of in-plane singular stress fields at cracks and multi-material corners
TL;DR: In this paper, the scaled boundary finite-element method is extended to analyze the in-plane singular stress fields at cracks and multi-material corners, where the singular functions are represented analytically and are not evaluated close to the singular point.

Mechanisms of Bimaterial Attachment at the Interface of Tendon to Bone
TL;DR: This work identifies four strategies to that the body adopts to achieve effective load transfer between tendon and bone and studies these strategies both in terms of ways that biomimetic attachment might benefit engineering practice, and in ways that engineering experience might serve to improve surgical healing outcomes.

Stress Singularities Resulting From Various Boundary Conditions in Angular Corners of Plates in Extension
TL;DR: In this paper, the authors investigated three boundary conditions on the radial edges: free-free, clamped-clamped, and clamped free, and showed that the free free extensional plate behaves locally at the origin exactly the same as a clampedclamped plate in bending, independent of Poisson's ratio.

Stress singularities in a two-material wedge
V. L. Hein,Fazil Erdogan +1 more
Abstract: A method for the determination of stresses in a two-material wedge-shaped region is presented. The method is applicable for plane strain or plane stress problems and treats the general case where each region is a wedge of arbitrary angle. The results are obtained by the use of the Mellin transform and the theory of residues. The characteristic equation is investigated to determine the stress singularity resulting from certain combination of geometry and material properties. A formal solution is then presented for the case where the loading is in the form of a point dislocation along the interface. This solution is the Green's function for the more general mismatch problems and therefore has applications in solving other problems with compatible boundary conditions. The results obtained show that for small values of r the dominant effect is due to geometry and the secondary effect is caused by the choice of elastic constants of the materials.
