Preamble
There are already several decent tools for the analysis of composite layups available on the MATLAB File Exchange, so why add another?
Layup Analysis Tool is a comprehensive package which offers ABD matrix output, stress calculation, failure assessment and layup design optimisation within a convenient and simple-to-use file submission:
  • Definition of n-ply layups with user-defined fibre orientations
  • Support for user-defined orthotropic elastic material properties (per ply)
  • Support for variable thickness plies
  • Support for n evenly-distributed section points (per ply)
  • Computation of the A, B and D matrices, and their inverse
  • Computation of the equivalent extensional and bending moduli (symmetric layups)
  • Stress and strain calculation in X-Y and ply coordinates, based on applied forces and moments
  • Pretty MATLAB figures of through-thickness stresses and strains
  • Inclusion of thermal and hydroscopic loads
  • User-defined output locations: Face (top, middle, bottom), envelope or section point list
  • Evaluation of stress and strain-based static failure criteria (Maximum Stress, Tsai-Hill, Tsai-Wu, Azzi-Tsai-Hill and Maximum Strain)
  • Evaluation of stress-based damage initiation criteria based (Hashin's Theory and LaRC05)
  • Stacking sequence optimiser: Find the stacking sequence which minimises a user-selected criterion based on an objective function (maximum or mean). The optimiser algorithm takes advantage of the Parallel Computing Toolbox
With all of the above functionality in one place, I hope this submission adds value to the current offering!
Summary
[varargout] = abd.main(varargin) analyses a user-defined composite layup.
To get started with a calculation, simply run the helper function:
user_definitions
The methodology used by Layup Analysis Tool follows classical lamination theory (CLT) and assumes that the laminate obeys the Kirchhoff Hypothesis:
  1. Transverse shear is negligible (plane stress in each ply)
  2. Displacements u and v (in the plane of the lamina) are assumed to be linear functions of the thickness coordinate z (no warping)
