Abstract
This paper contains the descriptions and instructions of the use of Radio Shack TRS-80 Pocket Computer for the key calculations of stiffness and strength of sym metric composite laminates.
Specific programs are constructed, using BASIC language, to give instant computa tions on:
(1) In-Plane Stiffness of Symmetric Laminates
(2) Flexural Rigidity of Symmetric Sandwich Plates
(3) In-Plane Strength of Symmetric Laminates
(4) Flexural Strength of Symmetric Sandwich Plates
The formulas and equation numbers used in the programming are the same as that found in Tsai and Hahn's "Introduction to Composite Materials" (Technomic, 1980). Listings of the programs are included along with flow diagrams, operation charts and memory contents.
It would be a simple matter to run the program on a variety of minicomputer systems by altering the syntax as appropriate.
