  • A Bayesian estimation method for variational phase-field fracture problems 
    Khodadadian, Amirreza; Noii, Nima; Parvizi, Maryam; Abbaszadeh, Mostafa; Wick, Thomas; Heitzinger, Clemens (Berlin : Springer, 2020)
    In this work, we propose a parameter estimation framework for fracture propagation problems. The fracture problem is described by a phase-field method. Parameter estimation is realized with a Bayesian approach. Here, the ...
  • Numerical modelling and validation of thermally-induced spalling 
    Berardone, Irene; Kajari-Schröder, Sarah; Niepelt, Raphael; Hensen, Jan; Steckenreiter, Verena; Paggi, Marco (London : Elsevier Ltd., 2015)
    In order to reduce the silicon consumption in the production of crystalline silicon solar cells, the improvement of sawing techniques or the use of a kerf-less process are possible solutions. This study focuses on a ...
  • Numerical recipes of virtual element method for phase field modeling of brittle fracture 
    Liu, Tong-Rui; Aldakheel, Fadi; Aliabadi, M.H. (Amsterdam : Elsevier, 2024)
    In this work, a new and efficient virtual element formulation for non-standard phase field model of brittle fracture is presented. A multi-pass alternative minimization solution scheme based on algorithm operator splitting ...
  • Simulation of Spalling with a Non-planar Bi-layered Interface Due to the Reuse of the Substrate 
    Berardone, Irene; Hensen, Jan; Steckenreiter, Verena; Kajari-Schröder, Sarah; Paggi, Marco (London : Elsevier Ltd., 2016)
    Kerfless wafering techniques have the potential to reduce the cost of crystalline silicon (Si) in photovoltaics by saving material and production costs. Thermomechanical spallation from thick wafers with aluminium (Al) in ...
