The Institute for Biomedical Engineering at the University and ETH Zurich, Switzerland and MEDISIM at École Polytechnique/INRIA Paris, France jointly develop Magnetic Resonance image-guided computational models of the heart. As part of our efforts to predict growth and remodeling of the failing heart we are offering a PhD position on image-guided Computational Cardiac Mechanics. See details in attached documents.
Abstract
This paper presents a design methodology based on a combination of isogeometric analysis (IGA),
level set and point wise density mapping techniques for topology optimization of piezoelectric /
flexoelectric materials. The fourth order partial differential equations (PDEs) of flexoelectricity,
which require at least C 1 continuous approximations, are discretized using Non-Uniform Rational
B-spline (NURBS). The point wise density mapping technique with consistent derivatives is
1. Is there anyone familiar/working with the time integration schemes for 2D dynamic crack propagation in XFEM? I would like to discuss some of the issues I am facing. I will really appreciate any kind of help/suggestions!
2. I tried to implement the time integration scheme proposed by Combescure et. al (An energy-conserving scheme for dynamic crack growth using the extended finite element method). But I am not sure about some of the strategies they are following in that paper. Anyone can clarify some of the questions I have?
Soft elastic layers with top and bottom surfaces adhered to rigid bodies are abundant in biological organisms and engineering applications. As the rigid bodies are pulled apart, the stressed layer can exhibit various modes of mechanical instabilities. In cases where the layer’s thickness is much smaller than its length and width, the dominant modes that have been studied are the cavitation, interfacial and fingering instabilities. Here we report a new mode of instability which emerges if the thickness of the constrained elastic layer is comparable to or smaller than its width.
In this paper we are concerned with finding exact solutions for the stress fields of nonlinear solids with non-symmetric distributions of defects (or more generally finite eigenstrains) that are small perturbations of symmetric distributions of defects with known exact solutions. In the language of geometric mechanics this corresponds to finding a deformation that is a result of a perturbation of the metric of the Riemannian material manifold. We present a general framework that can be used for a systematic analysis of this class of anelasticity problems.
The size- and shape-dependency of the chemo-mechanical behavior of spherical and ellipsoidal nanoparticles in Li-ion battery electrodes are investigated by a stress-assisted diffusion model and 3D finite element simulations. The model features surface tension, a direct coupling between diffusion and elasticity, concentration-dependent diffusivity, and a Butler-Volmer relation for the description of electrochemical reactions that is modified to account for mechanical effects.
