ContactMechanics
Contact mechanics with Python. This code implements computation of contact geometry and pressure of a rigid object on a flat elastic half-space. All calculations assume small deformations; in that limit, the contact of any two objects of arbitrary geometry and elastic moduli can be mapped on that of a rigid indenter on an elastic flat.
The methods that are implemented in this code are described in various papers:
- Fast-Fourier transform (FFT) for the computation of elastic deformation of periodic substrates.
- Decoupling of images for non-periodic calculation with the FFT.
- Hockney, Methods Comput. Phys. 9, 135 (1970)
- Liu, Wang, Liu, Wear 243, 101 (2000)
- Pastewka, Robbins, Appl. Phys. Lett. 108, 221601 (2016)
- Fast solution of nonadhesive, hard-wall interactions.
- Contact plasticity.
