Prediction of Cleavage Probability Using Higher Order Terms of the Crack Tip Field
نویسندگان
چکیده
The dependence of the Weibull stress is investigated on the parameters of the elasticplastic crack tip field. The general form of the Weibull stress is given for a three-parameter approximation of the elasto-plastic crack tip field. This is the basis to define a constraint correction of the critical value of the J-integral for cleavage fracture.

Prediction of Crack Initiation Direction for Inclined Crack Under Biaxial Loading by Finite Element Method
This paper presents a simple method based on strain energy density criterion to study the crack initiation angle by finite element method under biaxial loading condition. The crack surface relative displacement method is used to eliminate the calculation of the stress intensity factors which are normally required. The analysis is performed using higher order four node quadrilateral element. The...

In this paper, the present investigation has been conducted keeping in mind some of the problems concerning the crack propagation direction and growth under constant loading in an inclined crack geometry. The present studies mainly focused on the development and modifications in the crack growth criterion to account the biaxial, shear loading and number of stress terms. Existing criteria for th...
متن کاملA two dimensional Simulation of crack propagation using Adaptive Finite Element Analysis
Finite element method (FEM) is one of the most famous methods which has many applications in varies studies such as the study of crack propagation in engineering structures. However, unless extremely fine meshes are employed, problem arises in accurately modelling the singular stress field in the singular element area around the crack tip. In the present study, the crack growth simulation has b...
متن کاملEffect of Crack Geometry on Dislocation Nucleation and Cleavage Thresholds
A continuum model based upon the Peierls-Nabarro description of a dislocation ahead of a crack is used to evaluate the critical mode I loading for dislocation nucleation at the tip of a finite, pre-blunted crack. A similar approach is used to evaluate the critical mode I loading for atomic decohesion. Results are presented for various crack tip root radii (a measure of bluntness), for several c...
متن کاملThe boundary-layer effect on the crack tip field in mechanism-based strain gradient plasticity
The theory of mechanism-based strain gradient (MSG) plasticity involves two material length parameters, namely the intrinsic material length l and the mesoscale cell size lε, which are on the order of a few microns and 0.1 μm, respectively. Prior studies suggest that lε has essentially no effect on the macroscopic quantities, but it may affect the local stress distribution. We demonstrate in th...
