FEM Techniques Comparison for SIF Computing 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

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

Pour cela, nous présenterons également, dans les deux premiers chapitres de cette thèse, la mise au point des réactions de condensation de Hantzsch et de Biginelli en décrivant

We conclude that the free boundary and weighted shear stabilizations conside- rably improve the numerical results for this particular membrane-dominated shell problem, but also

method by potential energy derivation which corresponds numricaly to elastic solution post-processing of a cracked solid by a contour integration computation via Gauss points. The

• In the first case, the linear part of the algorithm amounts to replacing F by F 0 and solving an instance of modular composition modulo hTi, with parameter e 0 ; we use Theorem 5

The influence of a population of randomly-oriented cracks on the macroscopic thermal and linear- elastic response of a hexagonal polycrystal is addressed using a
