Version 0.4.0

New features

• new module for panel flutter analysis (compmech.aero)
  • flutter of unstiffened flat plates (compmech.aero.pistonplate)
    • with various boundary conditions
  • flutter of stiffened flat plates (compmech.aero.pistonstiffplate)
    • any combination of simply supported and clamped
    • blade stiffeners with flange modeled as 1D Saint Venant bars
    • stiffeners may have a pad-up modelled as a 2D shell following the skin displacement field

    • stiffeners modeled as 1D Saint Venant bars
    • stiffeners may have a pad-up modelled as a 2D shell following the skin displacement field
• new module for plate buckling (compmech.plate)
  • the Bardell shape functions
    • any combination of boundary conditions: simply supported, clamped and free
