Package for calculation of Q factors of strained beams with non-uniform width and thickness together with supplementary theory note. Possible boundary conditions are doubly clamped or Floquet-periodic Used for calculations published in "Generalized dissipation dilution in strained mechanical resonators", "Elastic strain engineering for ultralow mechanical dissipation" and "Clamp-tapering increases the quality factor of stressed nanobeams".
