FATIGUE TO FRACTURE INTEGRITY ASSESSMENT IN ENGINEERING AND BIOMEDICAL ENGINEERING
Degradation of structural integrity and fatigue life estimation remain critical challenges in engineering, including biomedical applications. Fracture mechanics and crack propagation prediction are highly sensitive to material parameters, with the Stress Intensity Factor being the most significant physical parameter for the estimation of crack stre...

MODELLING OF DAMAGE IN COMPOSITES USING SMOOTH PARTICLE HYDRODYNAMICS METHOD
This paper aims at the development and implementation of an algorithm for the treatment of damage and fracture in smooth particle hydrodynamic (SPH) method, where free surface, crack opening, including its propagation and branching is modelled by weakening the interparticle interactions combined with the visibility criterion. The model is consisten...

FATIGUE ANALYSIS BASED ON FATIGUE FAILURE APPROACH AND DAMAGE TOLERANT APPROACH IN CORONARY STENT DESIGN
Over the last few decades, cardiovascular stents have emerged as crucial biomedical devices. Stents undergo cyclic physiological loading, which can lead to progressive accumulation of structural damage over time eventually resulting in a stent fracture. Considering the critical role of stents, it is necessary to assess their fatigue endurance and p...
