In this paper, a computational framework for simulating ductile fracture in multipatch shell structures is presented. A phase-field model at finite strains combined with an isogeometric Kirchhoff–Love formulation. For the application to complex structures, we employ penalty approach imposing, patch interfaces, displacement and rotational continuity C0 C1 of phase-field, latter required if highe...

Heat treatment has a significant impact on the microstructure and mechanical properties of Al-Mg-Si alloys. The present study presents first Phase-Field modelling approach recrystallisation grain growth mechanism during annealing. It focuses precipitate fraction, radius, Mg-Si concentration in matrix phase, which are used as input data for calculation yield strength hardness at end different ag...

earthquake ground-motions show significant variability in both spectral and temporal characteristics. procedures to generalize and predict strong ground motions may be generally divided into three main disciplines: numerical techniques based on a kinematic source description, empirical attenuation models, and semi-empirical stochastic models. numerous studies have shown that, in the near-fault ...
