Constitutive modelling

Polymer Packaging Modeling Engineer at Procter & Gamble

Submitted by Jim Shepherd on

Description

The selected individual will lead the development, initial application and deployment of new modeling capability in the area of thermoplastic packages. The initial focus is on developing best in class material models across a range of polymers. This material modeling capability will be leveraged globally for a broad range of packaging model applications (blow molding, parison / preform optimization, empty and full bottle interaction with packing lines, etc.)

Constitutive models for rubber

Submitted by Italo Persechino on

Hi.

I found a very useful explanation about hyperelasticity here: http://en.wikipedia.org/wiki/Hyperelastic_material#cite_note-Ogden-1

 In the proof3, there is a good explanation (I can't found anything better than this one) of how we can express the Cauchy stresses in terms of the principal streches.

I am interested to incompressible material, so this is the equation:

VABS 3.6 Reduces Realistic Composite Blade Modeling to Seconds

Submitted by allanwood on

AnalySwift, LLC, a leading provider of efficient high-fidelity modeling software for aerospace and energy composites and other advanced materials, announced today the release of VABS 3.6. This is the latest version of VABS, which is the tool of choice for efficient and accurate modeling of composite slender structures such as wind turbine blades, helicopter rotor blades, high aspect ratio wings, composite bridges, and other slender structural components.

St. Venant-Kirchhoff constitutive law in Abaqus

Submitted by Mike Graham on

I would like to conduct simulations in Abaqus using a St.
Venant-Kirchhoff constitutive law, but when I try to define a material
in Abaqus CAE I do not see it as an option.

 

Is this available as a
built-in model?

 Is this just another material model with a parameter set to a specific value? (Hyperelasticity isn't my strongest area.)

ABAQUS and Constitutive equation

Dear all,

 I'm new to ABAQUS and I was wondering if we could have access to any constitutive equation in ABAQUS and add another stress tensor to the Cauchy stress tensor?

 regards,
