A Life Prediction Algorithm Implemented in P3 Using PCL

摘要

A life prediction methodology is implemented in P3 through a computer program, Probable Cause, written in Patran Command Language (PCL). The software uses finite element analysis data, and probabilistic material parameters to predict the component life and probability of survival for the analysis model. Probable Cause is imbedded in P3 and is accessed through a graphical user interface called from the main menu bar. The theory in Probable Cause is briefly outlined in this paper and its use is demonstrated with a finite element analysis of a jet engine turbine disk. The usefulness of PCL in accomplishing a task of this nature is shown and the lessons learned in the development process are discussed.
