Original abstract
The paper compares computational simulations of tension and bending tests on the basis of an anisotropic hyperelastic constitutive model with experimental results. The tested specimens are made of rubber with a single family of textile fibres under different angles. As our previous studies have shown substantial discrepancies between computational and experimental results, now we used textile fibres (with zero bending stiffness) instead of steel wires and the matrix was made of rubber with a very limited Mullins effect to eliminate the possible causes of errors. The results have shown that the simulations correspond well to the experiments.
