The Non-Linear Temperature Dependent Stiffness of Precompressed Rubber Cylinders

A shape factor based non-linear model of a rubber cylinder‘s temperature and preload dependent static stiffness is presented. The influence of temperature, precompression, material parameters, cylinder length and diameter, are investigated; with the motion split into a homogeneous thermal expansion including a globally equivalent preload deformation. Stiffness depends strongly on preload, particularly in larger shape […] mehr...

Molecular Dynamics Simulation Study1 – Localization and Multi-Flip Effects in a Single Polymer Chain on a Surface

We perform physical adsorption of a single globular chain on a surface of hemispherical shape by means of molecular dynamics. The surface is a smoothened spheric cap designed to imitate a small portion of the roughness of a filler particle like carbon black. For the chain we take advantage of a united atom model. Interactions […] mehr...

Determining Energy of Rubber Cylinders Using FEA

The objective of this study was to calculate strain energy for a rubber cylinder using finite element analysis (FEA) and compare using analytical equations for simple extension, bonded tension, and bonded compression. Constitutive laws were derived for simple extension including linear, large deformation, and hyperelastic material models. The strain energy or work done on the […] mehr...
