PROBABILISTIC DESIGN OF ADVANCED COMPOSITE MATERIALS FOR AEROSPACE STRUCTURES

摘要

In the present work the authors outline a procedure to evaluate uncertainity propagation in composite mechanical characteristics and to compute probability of failure of a composite laminate under generic static loads in according to the available literature. A review of probabilistic analysis basic concepts and methods is firstly introduced. A software is developed by authors, based on FORM and SORM, in order to perform analysis on a test case. Preliminary results obtained for a test case, are presented in the paper and compared with Monte Carlo simulation.
