FEM Techniques Comparison for SIFComputing of Cracked Plate

Let us note here, that there exist other numerical methods to determine singularities, such as the singularity exponent estimation based on classical nite element [28] and the

After numerous numerical works developed in various contexts of mechanics, the first a priori error estimate results for XFEM (in linear elasticity) were recently obtained in [13]

The thermodynamic force associated to the sliding has the mechanical meaning of the force acting in order to make the crack slide.. Yield surface is defined as a limitation of

Based on the obtained results a simple equation is presented for the equivalent permeability of a randomly cracked porous material as a function of the matrix permeability and the

The first one consists to extrapolate the nodal displacements near the cracked tip using a refined triangular mesh with T3 and T6 special elements, while the

A modified version of this estimate, called Full Range IDD by Zheng and Du, yields good results when comparing all poromechanical coefficients predicted by the estimate to
