Using MATLAB to Design and Analyse Composite Lami-nates

Abstract

This work deals with the generation of MATLAB script files that assists the user in the design of a composite laminate to operate within safe conditions. The inputs of the program are the material properties, material limits and loading conditions. Equations based on Hooke’s Law for two-dimensional composites were used to determine the global and local stresses and strains on each layer. Failure analysis of the structure was performed via the Tsai-Wu failure theory. The output of the program is the optimal number of fibre layers required for the composite laminate, as well as the orientation of each layer

Failure Analysis of Composite Laminates under Biaxial Tension: A Review and Framework

“…Ramsaroop and Kanny [6] generated MATLAB script files in order to design the laminated composites which gave better safety conditions. The global and local stresses and strains for each layer were determined using equations of Hooke's Law for two dimensional composites.…”

Review of composite – laminated material analysis in MATLAB using Piezo – electric sensor and actuator

“…Matlab code was given for the matrix, representing the stiffness of the laminated composite and numerical case study examples were provided to show the change from isotropic material to the laminated and orthotropic composite plates to improve the topology. The work in paper Ramsaroop et al [18] manages the production of MATLAB text records that help the user in planning a composite layer to work in safe conditions. Program inputs are material properties, material cutoff points, and stacking conditions.…”
