An adaptive acceleration scheme for phase-field fatigue computations
Jonas Heinzmann, Pietro Carrara, Marreddy Ambati +2
Phase-field models of fatigue are capable of reproducing the main phenomenology of fatigue behavior. However, phase-field computations in the high-cycle fatigue regime are prohibit…
DA-VEGAN: Differentiably Augmenting VAE-GAN for microstructure reconstruction from extremely small data sets
Yichi Zhang, Paul Seibert, Alexandra Otto +3
Microstructure reconstruction is an important and emerging field of research and an essential foundation to improving inverse computational materials engineering (ICME). Much of th…
Microstructure Characterization and Reconstruction in Python: MCRpy
Paul Seibert, Alexander Raßloff, Karl Kalina +2
Microstructure characterization and reconstruction (MCR) is an important prerequisite for empowering and accelerating integrated computational materials engineering. Much progress…
Phase-field modelling and analysis of rate-dependent fracture phenomena at finite deformation
Franz Dammaß, Karl A. Kalina, Marreddy Ambati +1
Fracture of materials with rate-dependent mechanical behaviour, e.g. polymers, is a highly complex process. For an adequate modelling, the coupling between rate-dependent stiffness…
Descriptor-based reconstruction of three-dimensional microstructures through gradient-based optimization
Paul Seibert, Alexander Raßloff, Marreddy Ambati +1
Microstructure reconstruction is an important cornerstone to the inverse materials design concept. In this work, a general algorithm is developed to reconstruct a three-dimensional…
Reconstructing random heterogeneous media through differentiable optimization
Paul Seibert, Marreddy Ambati, Alexander Raßloff +1
Microstructure reconstruction is a key enabler of process-structure-property linkages, a central topic in materials engineering. Revisiting classical optimization-based reconstruct…
A novel framework to model the fatigue behavior of brittle materials based on a variational phase-field approach
P. Carrara, M. Ambati, R. Alessi +1
A novel variational framework to model the fatigue behavior of brittle materials based on a phase-field approach to fracture is presented. The standard regularized free energy func…
Phase-field modeling of brittle fracture with multi-level hp-FEM and the finite cell method
Sindhu Nagaraja, Mohamed Elhaddad, Marreddy Ambati +3
The difficulties in dealing with discontinuities related to a sharp crack are overcome in the phase-field approach for fracture by modeling the crack as a diffusive object being de…
