DAMASK – The Düsseldorf Advanced Material Simulation Kit for modeling multi-physics crystal plasticity, thermal, and damage phenomena from the single crystal up to the component scale
Franz Roters,Martin Diehl,Pratheek Shanthraj,Pratheek Shanthraj,Phillip Eisenlohr,C. Reuber,Su Leen Wong,Tias Maiti,A. Ebrahimi,Thomas Hochrainer,Helge-Otto Fabritius,Svetoslav Nikolov,Martin Friák,Martin Friák,Martin Friák,N. Fujita,Nicolò Grilli,K.G.F. Janssens,N. Jia,P. J.J. Kok,Duancheng Ma,Felix Meier,Ewald Werner,Markus Stricker,Daniel Weygand,Dierk Raabe +25 more
TL;DR: The Dusseldorf Advanced Material Simulation Kit (DAMASK) as mentioned in this paper is an open, flexible, and easy to use implementation to the scientific community that allows the use and straightforward implementation of different types of constitutive laws and numerical solvers.
Journal ArticleDOI
Integrated experimental-simulation analysis of stress and strain partitioning in multiphase alloys
Cemal Cem Tasan,Martin Diehl,Dingshun Yan,Claudio Zambaldi,Pratheek Shanthraj,Franz Roters,Dierk Raabe +6 more
TL;DR: In this paper, an experimental-numerical methodology is introduced to strengthen the integrated understanding of microstructure and mechanical properties of multiphase alloys, enabling joint analyses of deformation-induced evolution of the micro-structure, and the strain and stress distribution therein, down to sub-micron resolution.
Journal ArticleDOI
Strengthening and strain hardening mechanisms in a precipitation-hardened high-Mn lightweight steel
Mengji Yao,Emanuel David Welsch,Dirk Ponge,Seyed Masood Hafez Haghighat,Stefanie Sandlöbes,Stefanie Sandlöbes,Pyuck-Pa Choi,Michael Herbig,Ivan Bleskov,Tilmann Hickel,Marta Lipińska-Chwałek,Marta Lipińska-Chwałek,Pratheek Shanthraj,Christina Scheu,Stefan Zaefferer,Baptiste Gault,Dierk Raabe +16 more
TL;DR: In this article, the strengthening and strain hardening mechanisms in an aged high-Mn lightweight steel (Fe-30.4Mn-8Al-1.2C, wt.%) were studied by electron channeling contrast imaging (ECCI), transmission electron microscopy (TEM), atom probe tomography (APT) and correlative TEM/APT.
Journal ArticleDOI
Numerically robust spectral methods for crystal plasticity simulations of heterogeneous materials
TL;DR: In this article, the direct and mixed variational conditions for mechanical equilibrium and strain compatibility are formulated in a framework that couples them to a general class of non-linear solution methods, and optimal solution strategies are devised based on this and applied to an idealised dual-phase polycrystalline aggregate.
Journal ArticleDOI
An integrated crystal plasticity-phase field model for spatially resolved twin nucleation, propagation, and growth in hexagonal materials
Chuanlai Liu,Chuanlai Liu,Pratheek Shanthraj,Martin Diehl,Franz Roters,Shuai Dong,Jie Dong,Wenjiang Ding,Dierk Raabe +8 more
TL;DR: In this paper, a dislocation-based crystal plasticity model is employed to predict the heterogeneous distribution of stress, strain and dislocation activity and is coupled to a phase field model for the description of the nucleation, propagation, and growth of { 1 ¯ 012 } tensile twins.
