SOFTWARE

Two separate instructional software resources are available.

PROMAL: This software was first written in 1990 in QuickBasic and since then has gone through several content additions and rewritten for new Windows platforms. The latest version revised in 2013 is available for Windows XP and above. Only readers who have bought a personal copy of the textbook (books bought by a library are excluded for obvious reasons) and meet certain criteria are authorized to download or use PROMAL.

MATLAB FUNCTIONS FOR COMPOSITES: The software is a library of MATLAB functions that can be used by students to write MATLAB programs for lamina and laminate analysis. Each function is accompanied by a MATLAB test file to show usage. A usage document is also given to clearly delineate the purpose of the function, inputs and outputs.

This software was written as a community class project by students of Fall 2012 and Fall 2013 in the Composites elective at USF, and put in the final format by Daniel Boston, Trey Moore, and Autar Kaw.
