An EigenValue Stabilization Technique for Immersed Boundary Finite Element Methods in Explicit Dynamics
Sascha Eisenträger, Lars Radtke, Wadhah Garhuom +4
The application of immersed boundary methods in static analyses is often impeded by poorly cut elements (small cut elements problem), leading to ill-conditioned linear systems of e…

Vibroacoustic simulations of acoustic damping materials using a fictitious domain approach
Lars Radtke, Paul Marter, Fabian Duvigneau +3
The numerical investigation of acoustic damping materials, such as foams, constitutes a valuable enhancement to experimental testing. Typically, such materials are modeled in a hom…
