Key Results

Enter geometry, material and interface details, then press Calculate.

Visualization

A stiffness-versus-deflection visualization is planned for a future release. The numeric results below capture the same relationships.

Underlying Principles

After the Python module loads, this section summarises the governing relationships and provides equation references straight from the engineering docstring.
