Determination of T-stress using finite element analysis

Science China Technological Sciences, 2017
A method that uses finite element analysis to determine the non-singular stress (T-stress) at a crack tip is proposed in this study. T-stress includes two components: the Tx-stress parallel to the tangent of the crack at its tip and the Ty-stress perpendicular to this tangent.

Evaluation of the T-stress for interacting cracks

Computational Materials Science, 2009
This paper investigates the T-stress for interacting cracks in general case. The cracks are located in an arbitrary position with the remote tension. If one uses the traction along crack face as unknown function, the problem for interacting cracks can be reduced to a Fredholm integral equation.

Multiaxial crack growth rate under variable T-stress

Engineering Fracture Mechanics, 2014
Abstract Fatigue crack growth rate are studied through experiments and numerical computations under different biaxial and mixed-mode loading conditions. Cruciform specimens under biaxial loading and compact tension–shear specimens are considered. The different degrees of mode mixity from pure mode I to pure mode II are given by the combinations of ...

On the consequences of T-stress in elastic brittle fracture

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2006
By using a generalized maximum tensile stress (MTS) criterion to predict onset of brittle fracture, it is shown that the presence of T-stress can have a significant effect on mode I and mode II toughness. The most prominent influence of T-stress on toughness occurs for mode II conditions.

T-Stresses for Edge Cracks and Vanishing Ligaments

Journal of Applied Mechanics, 2013
An edge-cracked half-plane 0 < x < A and a half-plane x > 0 with a semi-infinite crack x > a perpendicular to the edge are examined in this paper. Uniform crack-face loading is thoroughly examined, with a thorough exposition of the Koiter Wiener–Hopf approach (Koiter, 1956, “On the Flexural Rigidity of a Beam Weakened by Transverse Saw Cuts,

T-stresses in rectangular plates and circular disks

Engineering Fracture Mechanics, 1998
The aim of the present note is to compile T-stress results for a number of rectangular components and circular disks under different loadings. In addition, Green’s function representations are proposed, which enable the determination of T for arbitrarily given stress states (residual stresses, thermal stresses) in the uncracked body and a method is ...

Estimations of the T-stress for small cracks at notches

Engineering Fracture Mechanics, 2004
The T-stress is increasingly being recognized as an important additional stress field characterizing parameter in the analysis of cracked bodies. Using T-stress as the constraint parameter, the framework of failure assessments including the constraint effect has been established; and the effect of T-stress on fatigue crack propagation rate has been ...

T-stress and its implications for crack growth

Engineering Fracture Mechanics, 2002
Abstract Some of the “irregular” crack growth behaviour observed in different specimen geometries may not be unrelated. Discrepancies in fatigue crack growth rate have been observed in different specimen geometries of the same material; crack front “tunnelling” and out-of-plane crack growth have been found in mode I tension at elevated temperature ...
