Hyperelasticity, Rubber Material Deflection:
Given four different rubber, electronic, cabinet seals (click on 1st button of top row below), what is the seal, surface, pressure as a function of displacement? Pick that design which exhibits the highest seal pressure at the cabinet, doors', final, seating, position, for which the positional tolerance can vary from assembly to assembly.

Special features:
2D model setup with hyper-elastic material model for rubber, contact surfaces with friction between rubber seal and displacement block, and actuators to meter displacement of seal by moving displacement block a prescribed distance.

Output:
Nodal displacements and nodal, reaction, forces of displacement block. Since the 2D cross-sectional depth is one (1) inch, the nodal, reaction, forces are given per lineal inch. Use a spreadsheet to calculate the seal pressure (sum of the nodal reaction forces on the actuator elements divided by the rubber contact surface area - click on 2nd button of top row of thumbnails above).

Comments:
Designs C and D had interrupted contacts, that is, the contact surface split as the displacement progressed (click on 2nd row of buttons below).
