A thermodynamically consistent phenomenological model for ferroelectric and ferroelastic hysteresis
Barbara Kaltenbacher, Pavel Krejci
We propose a hysteretic model for electromechanical coupling in piezoelectric materials, with the strain and the electric field as inputs and the stress and the polarization as out…
Relaxation of regularity for the Westervelt equation by nonlinear damping with application in acoustic-acoustic and elastic-acoustic coupling
Rainer Brunnhuber, Barbara Kaltenbacher, Petronela Radu
In this paper we show local (and partially global) in time existence for the Westervelt equation with several versions of nonlinear damping. This enables us to prove well-posedness…
Absorbing boundary conditions for the Westervelt equation
Barbara Kaltenbacher, Igor Shevchenko
The focus of this work is on the construction of a family of nonlinear absorbing boundary conditions for the Westervelt equation in one and two space dimensions. The principal ingr…
Enhanced choice of the parameters in an iteratively regularized Newton-Landweber iteration in Banach space
Barbara Kaltenbacher, Ivan Tomba
This paper is a close follow-up of Kaltenbacher and Tomba 2013 and Jin 2012, where Newton-Landweber iterations have been shown to converge either (unconditionally) without rates or…
