Semi-analytical methods for plates, shells and stiffened panels
- Linear static analyses, with field outputs of displacements, strains and stresses
- Linear buckling
- Vibration, with or without pre-stress
- Panel flutter using the piston theory
- Geometrically non-linear static analyses (postbuckling) using the Newton-Raphson method or the arc-length methods of Riks and Crisfield
- Multi-domain assemblies of cylinders, stiffened panels and panels with debonding defects
The structural matrices are solved with structsolve.

History
See CHANGELOG.md for the details of each version.
- version 0.6.9 (2026-09-18)
- Fixed
StiffPanelBay.add_paneland the partial-domain integration ofShell.calc_kC,calc_kGandcalc_kM - Fixed the argument handling of the stiffness API: an invalid
corc_cteno longer reaches the nogil kernels, and a model that needs a radius raises instead of computing withr = 0 - Reproduction of Stamatelos and Labeas (Computation 2023, 11, 110) in
notebooks/stamatelos_labeas_2023.ipynb - Tangent stiffness matrix that is the exact derivative of the internal force vector, giving quadratic convergence to the Newton-Raphson method
ShellandMultiDomaincan be passed directly tostructsolve.Analysis, including the arc-length methods- Gauss-Legendre points and weights from
scipy.special.roots_legendre - Modules of the models renamed without the
_bardellsuffix, and the legacy_bardellmodel names removed frompanels.modelDB.db - Sphinx documentation with usage examples
- Fixed
- versions 0.5.x
- Damaged multidomain connections
- up to version 0.3.x
- Multidomain methods for pristine structures
