Displacement Boundary Method For Orthotropic
Plates
Author(s)
G. Davi & A. Milazzo
Abstract
An alternative boundary element approach, called Displacement Boundary
Method, for orthotropic plate analysis is presented. The governing equations of
the problem are obtained from a variational principle in which a modified hybrid
functional is used. The independent variables are the generalised displacements
and generalised tractions on the boundary and the lateral deflection in the
domain. A superposition of regular, static fundamental solutions is used for the
approximation of displacements in the domain whereas shape functions and nodal
values are employed to model the boundary variables, i.e. displacements and
tractions. The stiffness matrix preserves the symmetry and definiteness properties
of the continuum. It involves integrals of regular kernels only in its definition and
is numerica
