A Dugdale–Barenblatt Model for a Plane Stress Semi-Infinite Crack under Mixed Mode Concentrated Forces
In this paper, a mixed mode Dugdale–Barenblatt model has been established for a semi-infinite crack in an ideally elastic-plastic thin plate loaded by a pair of self-equilibrating concentrated forces at the cr...

Debonding of the interface as 'crack arrestor'
In this paper, we studied the interface debonding when a crack perpendicularly approaches an interface between two dissimilar elastic materials. An interface toughness law was first defined according to an adh...

Stress singularities near the tip of a two-dimensional notch formed from several elastic anisotropic materials
In this paper, we studied the stress singularities near the tip of a two-dimension notch, which could be a crack tip, formed from several elastic materials, each of them may be generally anisotropic. By introd...

Finite element implementation of thermal weight function method for calculating transient SIFs of a body subjected to thermal shock
The thermal weight function (TWF) is a universal function, which is dependent only on the crack configuration and body geometry, and is independent of temperature fields. The TWF method is especially suitable ...
