I am a Mechanical Engineer with more than 5 years of experience in design and modeling, by using tools professionally for 3D modeling such as:
* My name is Hamza from Algeria I am interested in understanding, modeling, and optimizing the mechanical response of materials.
Phase-field modeling of crack propagation in two dimensional
the sixth edition of the International Conference on Mechanics and EnergyAt: Sousse, Tunisia
Study a phase-field model PFM for simulating complicated crack patterns in various structures, including crack propagation. The PFM is based on the strain decomposition for the elastic energy, which drives the evolution of the phase-field. Then numerical simulations of the plate contained a tow crack at the side of the plate. Crack propagation and coalescence in plates with multiple cracks with changing the crack position along the plate and showing the effect of the crack position.
Investigation fatigue crack initiation and propagation cruciform welded joints by (XFEM)
Frattura ed Integrità Strutturale (Fracture and Structural Integrity)
This study has used the strain energy density (SED) approach to evaluate the stress intensity factor (SIF) of cracked cruciform welded joints in Hardox 450 steel. The obtained results of simulation will be compared with those provided by J-integral methode for different enriched zones and contours based on the extended finite element method (XFEM) coupled with the level set technique (LST).
