On Stress Anlysis for a Hyperelastic Material

Performing a finite element analysis (FEA) on a hyperelastic material is difficult due to nonlinearity, large deformation, and material instability. This paper provides a brief review of the hyperelastic theory and discusses several important issues that should be addressed when using ANSYS. Analysis on a fatigue specimen is used as an example of one of our product development challenges upon w...

New Advancements in Silicone Adhesives for Wearable Medical Devices

Material suppliers are developing new silicone adhesives to support the rapid growth of the wearable medical device market over the next few years.

Hyperelastic Material Models of Rubber and Rubber-like Materials

ABSTRACT The variety of applications of rubber-like materials in different industrial areas is enormous. In the automotive industry rubber is utilized in tires, as engine and door seals, whereas in aerospace industry rubber rings are used in fuel systems. In other engineering fields, rubbers have been used in conveyor belts, meteorological balloons and vibration isolation bearings or shock and ...

Symmetric Hyperbolic Equations of Motion for a Hyperelastic Material

We offer an alternate derivation for the symmetric-hyperbolic formulation of the equations of motion for a hyperelastic material with polyconvex stored energy. The derivation makes it clear that the expanded system is equivalent, for weak solutions, to the original system. We consider motions with variable as well as constant temperature. In addition, we present equivalent Eulerian equations of...
