Abstract
A formulation for analysis of general cross-section properties
has been developed. This formulation is based on the stress-strain
states in the classic six equilibrium modes of a beam by
considering a finite thickness slice modelled by a single layer
of 3D finite elements. The displacement variation in the lengthwise
direction is in the form of a cubic polynomial, which is here
represented by Hermitian interpolation, whereby the degrees of
freedom are concentrated on the front and back faces of the slice.
The theory is illustrated by application to a simple cross-section
for which an analytical solution is available. The paper also
shows an application to wind turbine blade cross-sections and
discusses the effect of the finite element discretization on the
cross-section properties such as stiffness parameters and the location
of the elastic and shear centers.
