Fiber Composite Material Characterization: Applications of an Optimization Algorithm

摘要

This paper describes and flow charts a nonlinear programming algorithm which has proven to be very useful in analyzing fiber composite testing data. Applications include fatigue life and stress rupture life analyses, S-N curve fitting, stress-strain curve fitting, statistical strength characterization, and other modeling parameter estimation. The Appendix contains an example concerning stress-rupture life, the listing of a code which implements the nonlinear programming algorithm, and the input and output from the run.
