Sedighiani, K. (author), Traka, K. (author), Roters, Franz (author), Raabe, Dierk (author), Sietsma, J. (author), Diehl, Martin (author)Physics-based crystal plasticity models rely on certain statistical assumptions about the collective behavior of dislocation populations on one slip system and their interactions with the dislocations on the other slip systems. One main advantage of using such physics-based constitutive dislocation models in crystal plasticity kinematic...journal article 2022

Sedighiani, K. (author), Traka, K. (author), Roters, Franz (author), Sietsma, J. (author), Raabe, Dierk (author), Diehl, Martin (author)High-resolution three-dimensional crystal plasticity simulations are used to investigate deformation heterogeneity and microstructure evolution during cold rolling of interstitial free (IF-) steel. A Fast Fourier Transform (FFT)-based spectral solver is used to conduct crystal plasticity simulations using a dislocation-density-based crystal...journal article 2022

Sedighiani, K. (author), Shah, Vitesh (author), Traka, K. (author), Diehl, Martin (author), Roters, Franz (author), Sietsma, J. (author), Raabe, Dierk (author)The capability of high-resolution modeling of crystals subjected to large plastic strain is essential in predicting many important phenomena occurring in polycrystalline materials, such as microstructure, deformation localization and in-grain texture evolution. However, due to the heterogeneity of the plastic deformation in polycrystals, the...journal article 2021

(author), Springer, Hauke (author), Zaefferer, Stefan (author), Shah, Vitesh (author), Wong, Su Leen (author), Baron, Christian (author), Diehl, Martin (author), Roters, Franz (author), Ponge, Dirk (author)This is a viewpoint paper on recent progress in the understanding of the microstructure–property relations of advanced high-strength steels (AHSS). These alloys constitute a class of high-strength, formable steels that are designed mainly as sheet products for the transportation sector. AHSS have often very complex and hierarchical...journal article 2020

Diehl, Martin (author), Kertsch, Lukas (author), Traka, K. (author), Helm, Dirk (author), Raabe, Dierk (author)Low-alloyed steels with body-centered cubic crystal structure are a material class that is widely used for sheet metal forming applications. When having an adequate crystallographic texture and microstructure, their mechanical behavior is characterized by an isotropic in-plane flow behavior in combination with a low yield strength. The...journal article 2019
