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).
The material constant for C10, C20, C30 I get from the curve fitting equation from the True Stress vs Stretch Ratio.
