Furthermore, a Matlab skeleton script for analysis and design optimization of laminated composite plates using isoparametric finite elements is provided as basis for part of the assignments. Course Format and Work Load : The course will consist of a condensed session comprised of 5 full days of lectures, work on assignments, and discussions at AAU.
The strength of any given laminate under a prescribed set of loads is probably best determined by conducting a test. However, when many candidate laminates and different loading conditions are being considered, as in a preliminary design study, analysis methods for estimation of laminate strength become desirable.

N2 - In this work optimum stiffness design of laminated composite structures is performed using the commercially available programs ANSYS and MATLAB. Within these programs a Free Material Optimization algorithm is implemented based on an optimality condition and a heuristic update scheme.
Therefore, a composite laminate consists of a material resultant of layers (laminae) bonded together. In this program, the layers are considered continuous and orthotropic. It is possible to input different properties for each used material in the layers. The implementation uses the Classical Laminate Theory (CLT) for computations.
Instead step-by-step solutions of composite material mechanics problems are examined in detail using MATLAB. All the problems in the book assume linear elastic behavior in structural mechanics. The emphasis is not on mass computations or programming, but rather on learning the composite material mechanics computations and understanding of the ...

Matlab Truss Analysis Program Description To support the ideas developed here we will introduce some Matlab scripts at each point to demonstrate how the theory described can be implemented for computer calculation. This collection of scripts will build into a program that can analyse pin-jointed trusses. Various Examples of Two-Material Composite Beams Composite beams are constructed from more than one material to increase stiffness or strength (or to reduce cost). Common composite-type beams include I-beams where the web is plywood and the flanges are solid wood members (sometimes referred to as "engineered I-beams").
