Abstract This article considers a thin-walled hollow cylinder, which is composed of fibrous and swellable hyperelastic material. The fibers are arranged in two families they taken to be parallel within each fiber family. also assumed mechanically equivalent symmetrically disposed the ground substance At instant homogeneous swelling, material incompressible. studies interplay orientation, mechan...

A quadtree-based fully Eulerian finite volume approach for the simulation of fluid-structure interaction problems is presented. Both fluid and structure phases, which are assumed to be incompressible viscous, solved monolithically on whole computational domain. The discretization stencils limited first layer neighbors thus enhancing efficiency parallel computations while limiting numerical orde...

A biophysically based multilayer continuum model of the facial soft tissue composite has been developed for simulating wrinkle formation. The deformed state of the soft tissue block was determined by solving large deformation mechanics equations using the Galerkin finite element method. The proposed soft tissue model is composed of four layers with distinct mechanical properties. These include ...

A 3D finite element face model which geometry has been extracted from CT data is being used for implementing orofacial speech gestures and studying underlying muscle activations. This model consists of 3 layers of full and degenerated hexahedral elements. The simplified 5-parameter Mooney-Rivlin hyperelastic law has been used to account for nonlinear elastic properties of face tissues. Contact ...

The sealing performance of the rubber packer is vital importance for subsea retractable connector, and cross-sectional shape one most important factors affecting it. compression distance increased by 19.54% utilizing established two-dimensional numerical model. In addition, a new parameter called anti-shoulder extrusion variable was defined in this paper. Shoulder will not occur when using as c...

This study investigates the effects of different solid models on predictions of brain shift for three craniotomies. We created a generic 3D brain model based on healthy human brain and modeled the brain parenchyma as single continuum and constrained by a practically rigid skull. We have used elastic model, hyperelastic 1st, 2nd, and 3rd Ogden models, and hyperelastic Mooney-Rivlin with 2and 5-p...
