ABSTRACT
Today, computers and digital sciences are essential to model processes in order to extract information and present it in a framework exploitable for the researcher.
In this context, we have begun this study to solve the problems that some industrialists encounter, especially those that exploit API 5L X52 steel. The prototype we propose uses ABAQUS as a computing tool associated with a numerical calculation method (Finite Element Method), allowing a numerical evaluation of the Mode I stress intensity factor of a CT specimen of API 5L X52 steel.
The results obtained were compared with empirical results to evaluate the accuracy of our approach and a good agreement is observed.

Evaluation of mode III stress intensity factors for bi-material notched bodies using the fractal-like finite element method
The fractal-like finite element method (FFEM) is extended to compute the stress intensity factors (SIFs) for bi-material notched bodies subject to anti-plane shear loading. The notched bodies are formed by bonding two materials together (isotropic-...
Implementation of the virtual crack closure technique in engineering FE calculations
Virtual Crack Closure Technique (VCCT) for stress intensity factor (SIF) calculations was proposed 30 years ago. This technique has not yet been implemented in large commercial finite element codes. The intended aim of the paper is to show general ...
Coupled analysis of 3D structural-acoustic problems using the edge-based smoothed finite element method/finite element method
This paper presents a coupled ES-FEM/FEM method for structural-acoustic problems, in which the ES-FEM and FEM models are used to simulate the structure and the fluid, respectively. In the present coupled models, the triangular Reissner-Mindlin plate ...
