Author: Stephen Kirwa Melly, Liwu Liu, Yanju Liu, Jinsong Leng
Novelty/impact/significance
Improved the predictive capabilities of Carroll's model and demonstrated its finite element implementation for accurate simulation of elastomeric component behavior.
Scientific question
The inaccurate predictions of Carroll's model specifically in the equibiaxial loading mode has been solved.
Key of how
The original strain energy expression is modified to comply with the restriction that it should vanish at the undeformed configuration and a compressible term is added.
Major points
1. Carroll's model is improved by modifying the strain energy density expression.
2. Numerical and finite element predictions are compared with classical experimental data.
3. The modified version demonstrated superior predictive capabilities.
