A theoretical testing method for fully characterising the Mooney-Rivlin three-parameter hyper-elastic material model is proposed by capturing full-field digital image correlation (DIC) data, namely displacement field and indentation force data. finite element with known parameters will act as experimental against which all data be referenced (a preliminary test case). Going forward this stand-i...

In this work the unsteady non-Newtonian blood flow and mass transfer in symmetric and non-symmetric stenotic arteries are numerically simulated considering the fluid-structure interaction (FSI) using the code ADINA. Blood with hyperviscosity syndrome is considered and hyperelastic Mooney–Rivlin model is used for the compliant arterial wall. The inlet boundary condition of imposed velocity or pr...

A~tract. The finite amplitude, coupled shear-torsional motion of a circular disk supported between identical rubber spring cylinders is studied. The material of the springs is assumed to be an incompressible elastic material. The oscillatory motion of the disk is studied for two different cases. In the first case, the material of the spring is assumed to be an incompressible elastic material wh...

Abstract The airless tires are developed to overcome a disadvantage of pneumatic tire which lost maneuverability caused flattening and blasting. finite element analysis (FEA) is an effective method for development have complex construction. material properties describe mechanical behavior each component very important yield accurate result. high order constitutive model usually obtains the accu...

Atomic force microscopy is an established technique for probing the local elastic properties of materials at submicron scales. In some cases, linear elastic contact theories based on Hertzian and adhesive contact mechanics suffice to model the indentation process. However, at the large strains that are common in many nanoindentation experiments, the linear models become invalid. A force-indenta...

Abstract The transition of polymer adhesives from an initially liquid to a fully cured viscoelastic state is accompanied by three phenomenological effects, namely increase in stiffness and viscosity conjunction with decrease volume (curing shrinkage). Under consideration these phenomena, some us (Hossain et al. Computational Mechanics 46:363-375, 2010) have devised generic, finite strain framew...

This practice and experience paper describes a robust C++ implementation of several nonlinear solid 3D deformable object strategies commonly employed in computer graphics, named the Vega FEM simulation library. Deformable models supported include co-rotational linear FEM elasticity, Saint-Venant Kirchhoff FEM model, mass-spring system, and invertible FEM models: neo-Hookean, Saint-Venant Kirchh...

Understanding of the dynamic behaviour of the levator ani is important to the assessment of pelvic floor dysfunction. Whilst shape modelling allows the depiction of 3D morphological variation of the levator ani between different patient groups, it is insufficient to determine the underlying behaviour of how the muscle deforms during contraction and strain. The purpose of this study is to perfor...
