The electro-thermo-convection of a dielectric liquid in horizontal capacitor is investigated under the autonomous charge injection from cathode and heating above. In case DC electric field, linear stability analysis carried out, thresholds monotonic oscillatory instability are determined. finite difference method used for numerical simulation nonlinear behavior electro-thermo-convective pattern...

The concept of representative crack elements has been successfully introduced to phase-field fracture in previous publications, where anisotropic elasticity [1], visco-elasticity [2], elasto-plasticity and surface friction [3] are considered at small deformations. This framework allows overcome unrealistic predictions for the kinematics, reported e.g. Strobl Seelig [4], Steinke Kaliske [5], kno...

Abstract The derivation of nonlocal strong forms for many physical problems remains cumbersome in traditional methods. In this paper, we apply the variational principle/weighted residual method based on operator elasticity, thin plate, gradient electro-magneto-elasticity and phase-field fracture method. governing equations are expressed as an integral form support dual-support. first example sh...

2014 In order to explain the temperature dependence of elasticity of thermo-reversible gels, a simple model is proposed It assumes that the gel consists of Langevin chains whose both ends are loosely fixed in crystalline junction regions in such a way that the segments near each end are bound densely in one of the junction region. The segments are assumed to be released from the junction with i...

This study is purposed with the preparation of polyacrylamide/Polypyrrole hydrogel composite, in which the hydrogel of crosslinked polyacrylamide is a matrix and Polypyrrole is an electro-conducting component. The effects of synthesis conditions on the structure of the composite systems, their ability to swell in water, and mechanical characteristics are studied. The proposed synthesis procedur...

We introduce and study some scalable domain decomposition preconditioners for cardiac electro-mechanical 3D simulations on parallel HPC (High Performance Computing) architectures. The electro-mechanical model of the cardiac tissue is composed of four coupled sub-models: (1) the static finite elasticity equations for the transversely isotropic deformation of the cardiac tissue; (2) the active te...
