Damage model for soft polymer

Submitted by mahzanjohar on Wed, 10/08/2014 - 09:58

Hi all,

I'm working on modelling of adhesive joint using soft polymer adhesive types.

Can anyone suggest what are suitable damage mnodel for soft polymer.

I'm using Abaqus FE software version 6.12

Hyperelastic Materials

Pressure Sensitive Adhesive

Acrylic adhesive

Greetings,

I'm conducting a simple shear test (single lap joint) between aluminum bonded with 3M adhesive.

Adhesive material is 3M VHB 4930 adhesive (acrylic)

Result obtains =

Load vs Displacement Curve

True Stress vs Stretch Ratio

From the literature, mostly they used Yeoh model for 3M adhesive (Modeling and simulation of dielectric elastomer actuators,M.Wissler 2005).

Moisture absorption in adhesive

Dear all,

Need Help..

I'm doing research in moisture absorption in adhesive bonding. I'm wondering how to differentiate and characterize the Fickian Diffusion and Non-Fickian Diffusion during absorption and desorption moisture.

Thank You
