Reconstructing effective ultrasound transducer models via distributed source inversion
Tim Bürchner, Simon Schmid, Ernst Rank +2
Accurate modeling of ultrasound wave propagation is essential for high-fidelity simulation and imaging in ultrasonic testing. A primary challenge lies in characterizing the excitat…
Generalized eigenvalue stabilization for immersed explicit dynamics
Tim Bürchner, Lars Radtke, Sascha Eisenträger +4
Explicit time integration for immersed finite element discretizations severely suffers from the influence of poorly cut elements. In this contribution, we propose a generalized eig…
On the efficiency of explicit and semi-explicit immersed boundary finite element methods for wave propagation problems
Tim Bürchner, Lars Radtke, Philipp Kopp +3
Immersed boundary methods have attracted substantial interest in the last decades due to their potential for computations involving complex geometries. Often these cannot be effici…
Quantitative Comparison of the Total Focusing Method, Reverse Time Migration, and Full Waveform Inversion for Ultrasonic Imaging
Tim Bürchner, Simon Schmid, Lukas Bergbreiter +3
Phased array ultrasound is a widely used technique in non-destructive testing. Using piezoelectric elements as both sources and receivers provides a significant gain in information…
Implicit-Explicit Time Integration for the Immersed Wave Equation
Christian Faßbender, Tim Bürchner, Philipp Kopp +2
Immersed boundary methods simplify mesh generation by embedding the domain of interest into an extended domain that is easy to mesh, introducing the challenge of dealing with cells…
Isogeometric Multi-Resolution Full Waveform Inversion based on the Finite Cell Method
Tim Bürchner, Philipp Kopp, Stefan Kollmannsberger +1
Full waveform inversion (FWI) is an iterative identification process that serves to minimize the misfit of model-based simulated and experimentally measured wave field data, with t…
