Multiobjective Best Theory Diagrams for cross-ply composite plates employing polynomial, zig-zag, trigonometric and exponential thickness expansions

摘要: This paper presents Best Theory Diagrams (BTDs) for plates considering all the displacement and stress components as objectives. The BTD is a diagram in which minimum number of terms that have to be used achieve desired accuracy can read. Maclaurin, zig-zag, trigonometric exponential expansions are employed static analysis cross-ply composite plates. Equivalent Single Layer (ESL) approach considered, Unified Formulation developed by Carrera used. governing equations derived from Principle Virtual Displacements (PVD), Navier-type closed-form solutions adopted. BTDs obtained using Axiomatic/Asymptotic Method (AAM) genetic algorithms (GA). results show tool assess computational efficiency any structural models draw guidelines develop models. inclusion multiobjective capability extends validity recognition role played each output parameter refinement model.
