A popular version of the finite strain Maxwell fluid is considered, which is based on the multiplicative decomposition of the deformation gradient tensor. The model combines Newtonian viscosity with hyperelasticity of Mooney-Rivlin type; it is a special case of the viscoplasticty model proposed by Simo and Miehe (1992). A simple, efficient and robust implicit time stepping procedure is suggeste...

In this paper, equilibrium and stability of the von Mises truss subjected to a vertical load are analyzed from theoretical, numerical experimental points view. The bars composed rubber material, so that large deformations can be observed. analytical model is developed in fully nonlinear context finite elasticity constitutive behavior modeled using Mooney–Rivlin law. parameters identified by mea...

The purpose of this study is to construct a finite-element (FE) model of golf balls with hyperelasticity and viscoelasticity and to devise a method for construction of FE ball models by investigating the relationship between the material properties and the behaviour of the golf ball during and after impact. As for the material model of the FE ball model, the Mooney–Rivlin model and the three-el...

Abstract The famous bifurcation analysis performed by Flügge on compressed thin-walled cylinders is based a series of simplifying assumptions, which allow to obtain the landscape, together with explicit expressions for limit behaviours: surface instability, wrinkling, and Euler rod buckling. most severe assumption introduced use an incremental constitutive equation, does not follow from any non...

A biomechanical model is proposed for the growth of the brown alga Ectocarpus siliculosus Featuring ramified uniseriate filaments, this alga has two modes of growth: apical growth and intercalary growth with branching. Apical growth occurs upon the mitosis of a young cell at one extremity and leads to a new tip cell followed by a cylindrical cell, whereas branching mainly occurs when a cylindri...

Abstract NPTs have vast applications because of no tyre puncture, need for air pressure, low rolling resistance, and also higher flexibility design recyclability. In this research work, different structures polyurethane (PU) spokes been designed analyzed under radial loading conditions which include like honeycomb with varying cell angles, simple spoke, trapezoid type by keeping in view that th...

Recently, data-driven approaches in the field of material modeling have gained significant attention. A major advantage these is direct integration experimental results into models. Nevertheless, artificial neural networks (ANNs) are especially challenging to interpret from a physical point view, since internal processes ANNs difficult understand. In this work new automatic method for generatio...

Intracranial aneurysms (IA) are dilations of the cerebral arteries and, in most cases, have no symptoms. However, it is a very serious pathology, with high mortality rate after rupture. Several studies been focused only on hemodynamics flow within IA. besides effect flow, development and rupture IA also associated combination other factors such as wall mechanical behavior. Thus, objective this ...

In this current research, a commercial aircraft metallic leading edge structurally reinforced with Y-shaped and V-shaped plate system is numerically examined to investigate the effectiveness of such reinforcements against soft impacts, more commonly known as bird strikes in aviation industry. A non-linear finite element code Ansys Explicit adopted run virtual test cases. The computational model...

Abstract In additive manufacturing, also called 3-D printing, one of widely used materials is polylactide thermoplastic polymer (PLA) by means the fused deposition modeling. For weight reduction purposes, infill density an often feature in slicing for printing. We aim at investigating effect on mechanical properties structures. Therefore, we demonstrate how to prepare tensile specimens and test...
