a Finite element (FE) simulation of suction experiment using a neo-Hookean material model with Young’s modulus E. The 2D cross-sectional geometry is depicted. b Estimated kNimble and kR0 for two materials, M1 and M2, with FE analysis (FE stiffness) and mean (n = 3) of kNimble and kR0 (experimental stiffness). The dotted line indicates the linear relationship between kNimble or kR0 and the Young’s modulus of the material
