Returns A, B, C (numpy 2D arrays) of the laminate

property AllowShear: float#
property DampCoef: float#
property EqBenProps: tuple[float, float, float, float]#

Calculate the Equivalent Bending Properties of the laminate using D matrix

Returns:

A tuple containing (Ex, Ey, nu, G).

  • Ex: Equivalent Bending modulus in the x-direction.

  • Ey: Equivalent Bending modulus in the y-direction.

  • nu: Equivalent Bending Poisson’s ratio.

  • G: Equivalent Bending shear modulus.

Return type:

tuple[float, float, float, float]

Example

>>> pcomp: n2p.AllClasses.N2PComp = model.PropertyDict((20001, "0"))
>>> Ex, Ey, nu, G = pcomp.EqBenProps()
