Abstract: In this paper, a recently proposed material model (Sun model) that is based on the lower bound approach of plasticity is extended by introducing a family of dilatant plasticity theories. The ...

Abstract: Based on the analytical solution of Crouch to the problem of a constant discontinuity in displacement over a finite line segment in an infinite elastic solid, in the present paper, the crack-tip ...

Abstract: This paper presents a numerical approach to modeling a general system containing multiple interacting cracks and voids in an infinite elastic plate under remote uniform stresses. By extending ...

Abstract: This note can be regarded as a supplement of a paper entitled “On the Use of Approximation Methods for Microcrack Shilding Problems” (, 1992, ASME J. Appl. Mech.59, 497–501). In this note, ...

Abstract: This note deals with the stress intensity factors (SIFs) for double edge half-circular-hole cracks in a rectangular sheet in tension by means of the displacement discontinuity method with crack-tip ...

Abstract: The S–N equation is one of the most important equations in fatigue model investigation. A majority of fatigue models, including multi-axial fatigue model and mean effect models, are established on the basis of the S–N ...

Abstract: In the present paper, an improved strain-energy-density criterion presented recently for the commonly used fracture criterion, the minimum strain-energy-density criterion, is extended to the case ...

Abstract: This paper deals with crack(s) emanating from a hole in infinite elastic plate in tension. Such a crack problem is called a hole crack problem for short. By extending Buckner’s principle ...

Abstract: This brief deals with crack(s) emanating from a hole in infinite plate subjected to uniform internal pressure. Such a crack problem is called a hole crack problem for short. By using a hybrid ...
