Computation Of The Maximum Torque Of A Cap Liner Using A Power-Law Friction And Finite Element Analysis

This work looks at the experimental study and the finite element analysis of the maximum torque of a metal cap with a liner over a glass bottle. The cap liner is hyperelastic. The predicted maximum torque is then calculated by a numerical integration scheme over the contact surface, using an experimental coefficient of static friction (power-law) as a function of the normal pressure. The predicted torque shows good agreement with that measured through experiments.
