Prestress Optimization Of Laminated Plates
Author(s)
P. Procházka
Abstract
Recently, the author has published several papers on optimisation of cylin-
drical composite laminated structures by virtue of appropriate change of
prestresses in a certain sense (optimization of reinforcing prestresses for
given plies, the lay-ups and prestressing, thickness and prestressing, etc.).
Such optimization was mostly connected with minimization of the variance
of stresses acting in selected directions.
In this paper basically similar optimization is presented for laminated
plates. A priori prestress - stress relation is constructed by means of a
linear hull of external influences (external load, prestress). This leads to a
quadratic cost functional and, consequently, to a linear system of algebraic
equations.
1 Introduction
The laminated plates are solved by virtue of the Refined Reissner The-
ory (RRT), which is considered to hold in every la
