Plane Strain Deformations near the Tip of a Contacting Interfacial Crack in Locking Materials
نویسندگان
چکیده
Plane strain deformations near the tip of a crack between two homogeneous and isotropic linear elastic bodies are studied on the assumptions that the two surfaces on either side of the crack contact each other and that the dilatation everywhere in the body is greater than or equal to a constant. The region where the dilatation equals the constant is called the locking region. It is found that one of the two half planes is in the locking state and the singularity index equals l/2.

Analysis of Deformation Fields near an Interfacial Crack Tip in Locking Materials
We study plane strain deformations near a crack tip between two isotropic and homogeneous Hookean bodies and assume that deformations obey the constraint that the volume of a material element cannot become zero. The constraint is imposed by requiring that the dilatation everywhere in the body must be greater than or equal to a constant. The region where the dilatation equals the constant is cal...
متن کاملPlane Strain Deformations of Locking Materials near a Crack Tip
Plane-strain deformations of an isotropic and homogeneous Hookean body containing a crack are studied and it is required that the dilatation everywhere in the body be. greater than or equal to a constant. Following Prager, the region where the dilatation always equals the constant is identified as the locking region. For the case when the deformations of the body are symmetrical about the plane...
متن کاملPlastic Analysis of Mixed Mode Plane Stress Crack Problems
Two parameters are identified for characterizing the deformation in the plastic zone near the tip of a crack when mixed mode conditions prevail. Details of the near-tip stress and strain distributions are presented f or hardening materials in which a diffus e plastic zone occurs under plane stress conditions. For small scale yielding the two near-tip parameters are related to the two elastic s ...
متن کاملAsymptotic study of the interfacial crack with friction
We study a model of interfacial crack in which contact of the crack faces obeys a Coulomb law of friction. For such cracks, the possibility that the stress has a stronger singularity than rÿ1=2 near the tip has been reported. In this paper, we demonstrate that these strong singularities can, in fact, be discarded, because they would assume a backward propagation of the crack. In passing, we pro...
متن کامل/-Integral Estimates for Strain-Hardening Materials in Ductile Fracture Problems
A finite-element procedure is developed to analyze plane ductile fracture problems in the presence of largescale yielding near the crack tip. Strain and stress singularities near the crack tip, corresponding to the strainhardening material model, are embedded in elements near the crack tip. The developed elastic-plastic incremental finite-element method is based on a hybrid displacement model. ...
