Online Learning of Correspondences between Images

Michael Felsberg, Fredrik Larsson, Johan Wiklund +2

We propose a novel method for iterative learning of point correspondences between image sequences. Points moving on surfaces in 3D space are projected into two images. Given a poin…

A micromorphic phase-field model for brittle and quasi-brittle fracture

Ritukesh Bharali, Fredrik Larsson, Ralf Jänicke

The phase-field model for fracture, despite its popularity and ease of implementation comes with its set of computational challenges. They are the non-convex energy functional, var…

Phase-field fracture irreversibility using the slack variable approach

Ritukesh Bharali, Fredrik Larsson, Ralf Jänicke

In this manuscript, the phase-field fracture irreversibility constraint is transformed into an equality-based constraint using the slack variable approach. The equality-based fract…

On-the-fly adaptivity for nonlinear twoscale simulations using artificial neural networks and reduced order modeling

Felix Fritzen, Mauricio Fernández, Fredrik Larsson

A multi-fidelity surrogate model for highly nonlinear multiscale problems is proposed. It is based on the introduction of two different surrogate models and an adaptive on-the-fly…

Tangential differential calculus and the finite element modeling of a large deformation elastic membrane shell problem

Peter Hansbo, Mats G. Larson, Fredrik Larsson

We develop a finite element method for a large deformation membrane elasticity problem on meshed surfaces using a tangential differential calculus approach that avoids the use of c…
