A modified Levenberg-Marquardt method for estimating the elastic material parameters of polymer waveguides using residuals between autocorrelated frequency responses
Dominik Itner, Dmitrij Dreiling, Hauke Gravenkamp +2
In this contribution, we address the estimation of the frequency-dependent elastic parameters of polymers in the ultrasound range, which is formulated as an inverse problem. This i…

A massively parallel explicit solver for elasto-dynamic problems exploiting octree meshes
Junqi Zhang, Ankit Ankit, Hauke Gravenkamp +2
Typical areas of application of explicit dynamics are impact, crash test, and most importantly, wave propagation simulations. Due to the numerically highly demanding nature of thes…
