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...

Abstract Droplet vibration is an important phenomenon in many technical applications. Correctly predicting the occurring behaviour such as droplet detachment a challenge for numerical simulations. In this work, so‐called Navier‐Stokes‐Korteweg model that couples gas‐liquid phase field to Navier‐Stokes equations used simulate on horizontally vibrating surface. Additionally, equilibrium state of ...
