Determination of the full elastic-plastic stress field of a tensile crack by minimization of the complementary energy
In this paper, an energy method is proposed to study the full elastic-plastic field of a tensile crack. A statically admissible stress field is established by develo** an expansion of the stress function in ...

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 ...

Investigations of vehicle securing without lashings for Ro-Ro ships
To reduce the area on deck occupied by each car and the labour and time required for lashing and unlashing cars, it has been proposed by the author that in some conditions, cars on decks could be transported w...

Statistics of strength of ceramics: finite weakest-link model and necessity of zero threshold
It is argued that, in probabilistic estimates of quasibrittle structure strength, the strength threshold should be considered to be zero and the distribution to be transitional between Gaussian and Weibullian....
