On an optimization framework for damage localization in structures
Owais Saleem, Tim Suchan, Natalie Rauter +1
Efficient structural damage localization remains a challenge in structural health monitoring (SHM), particularly when the problem is coupled with uncertainty of conditions and comp…
Fracture propagation by using shape optimization techniques based on outer Riemannian metrics
Tim Suchan, Winnifried Wollner, Kathrin Welker
In this work, we investigate a novel approach for the simulation of two-dimensional, brittle, quasi-static fracture problems based on a shape optimization approach. In contrast to…
Shape optimization in the space of piecewise-smooth shapes for the Bingham flow variational inequality
Tim Suchan, Volker Schulz, Kathrin Welker
This paper sets up an approach for shape optimization problems constrained by variational inequalities (VI) in an appropriate shape space. In contrast to classical VI, where no exp…
Crack propagation in anisotropic brittle materials: from a phase-field model to a shape optimization approach
Tim Suchan, Chaitanya Kandekar, Wolfgang E. Weber +1
The phase-field method is based on the energy minimization principle which is a geometric method for modeling diffusive cracks that are popularly implemented with irreversibility b…
