Laminate Tool.xls



Purpose of calculation:
Provides Stiffness Matrices for Composite Laminate (A, B, D and Quasi Equivalent Ex and Ey)

Calculates Stress and Strain in Each Ply
Calculates Failure using Various Criteria (Tsai-Wu, Max-Stress, Max-Strain)
Calculation Reference
Barbero, E J. Introduction to Composite Materials.  1999 Taylor Francis Group.

Matched Results of sample problems in Barbero textbook
How to use this tool
1. Pick a material from the scroll bar on the 'Material Selector' toolbar. Material data available for E-Glass/ Epoxy, S-Glass/ Epoxy, E-Glass/ Isophtalic Polyster, Kevlar 49/ Epoxy, Carbon/ Epoxy AS4/3501-6, Carbon/ Epoxy T800/3900-2 and Carbon/ Epoxy IM7/8551-7.
2. Define your laminate on the "laminate def" tab. You need only enter a ply number, thickness and the orientation. There is a 29 ply limit.
3. Enter the known boundary condition on the "Stress Strain and Failure" tab.
