Dissertation
Grid generation and fluid-solid coupling methods for the investigation of gas turbine rotor blade internal cooling
TL;DR: In this paper, the authors proposed a robust and efficient viscous mesh generation method to construct the computational grid in a hybrid manner in order to mesh the complex 3D configurations efficiently for CFD analysis.

Computational Modelling of Fragmentation and Penetration of Ceramic Plates
G. T. Camacho,M. Ortiz +1 more
TL;DR: In this paper, a variety of ceramics are evaluated as candidate armor materials, as they possess an attractive combination of high hardnesses and low densities, however, brittleness can result in catastrophic failure in the form of extensive cracking, fragmentation and comminution.
High gradient XFEM for fracture mechanics
Safdar Abbas,Marek Behr +1 more
TL;DR: In this paper, a new enrichment scheme in the eXtended Finite Element Method (XFEM) is investigated, in which a high gradient field can be approximated on fixed meshes.

Forest density is more effective than tree rigidity at reducing the onshore energy flux of tsunamis
TL;DR: In this paper , the authors used a three-dimensional incompressible computational fluid dynamics model with a fluid-structure interaction approach to quantify how energy reflection and dissipation vary with different degrees of rigidity and vegetation density of a coastal forest.

A partitioned scheme for adjoint shape sensitivity analysis of fluid-structure interactions involving non-matching meshes
Reza Najian Asl,Ihar Antonau,Aditya Ghantasala,Wulf G. Dettmer,Roland Wüchner,Kai-Uwe Bletzinger +5 more
TL;DR: In this paper, a partitioned solution procedure is presented to compute shape gradients in fluid-structure interaction (FSI) using black-box adjoint solvers, where sub-adjoint problems are coupled with each other by augmenting the target functions with auxiliary functions, independent of the concrete choice of the underlying adjoint formulations.
