Waves on elastic plates
Project description
KLOVE
Numerical modelling of waves on thin elastic plates
klove
is a Python package designed to study wave propagation on thin elastic plates based on the
Kirchhoff–Love theory. The plate can be loaded with elements that will affect the propagation of elastic waves: the aim
is to find the solution to this problem numerically. Key features of the code are:
- Easy to use interface --- simply define the plate and scatterers (pins, masses, mass-spring or beam resonators).
- Multiple scattering simulations --- with plane wave and point load excitation.
- Far field quantities --- with plane wave excitation.
- Diffraction by gratings --- with calculation of efficiencies.
- Quasi-normal mode analysis and expansion --- by solving a nonlinear eigenvalue problem.
- Calculation of phononic band diagrams --- with utilities to define the path along the edges of the Brillouin zone.
- Auto-differentiable --- allowing for gradient-based optimization of elastic wave propagation.
