A Digital Algorithm for Composite Laminate Analysis - FORTRAN. Revision
Abstract
This report presents a FORTRAN computer code for the solution of composite materials problems. The computer program can conduct the point stress analysis of general laminates including hybrid laminates. The effect of hygrothermal and mechanical loads on the strength of composite laminates can be studied using this program. Strength predictions on the basis of six commonly used failure theories can be done. Plotting capabilities have been included- using a CALCOMP Plotter to obtain the failure envelopes in different loading planes for all the failure theories. A complete listing of the computer program is given. A number of typical laminates have been treated for numerical and graphical illustrations. Input and output parameters are explained in detail. The algorithm is written in an easily understandable format. Material properties for five different materials are stored in the program. The required material can be used by giving the material name for pure laminates and material property identification number in the layers data card for hybrid laminates. These quantities are given in SI units. If the results ae desired in English units (i. e., Psi etc.), a unit identification command has to be used in the appropriate place. This program is a modified version of an earlier program given in AFWAL- TR-81-4073 (AD-A108 201).
