Management

· Monitoring Responsable: Prof. P. Curtis (Dstl)

· Chairman: Prof. P. Curtis (Dstl)

Objectives

The objectives of the AG are the following:

· Establish the confidence in using an available probabilistic code for analysing composite structures;

· Establish the significance of batch-to-batch and manufacturer’s variability effects on laminate strength variability;

· Establish the suitability of using simplified strength predictive models for probabilistic analysis;

· Develop the statistical models accounting for batch-to-batch and manufacturer’s variability for the random variables considered;

· Establish the reliability of deterministically designed structures and investigate the potential gains of the probabilistically designed equivalent.

Main achievements

The Action Group has just started. A first meeting was held at the end of December 2004.

Resources

Resources		Year
		2001	2002	2003	2004	2005
Man-months	Actual/ Planned					P20
Other costs (in K€)	Actual/ Planned					P20

Benefits

The probabilistic methodology permits rapid theoretical predictions of stochastic material properties (such as strength). Structural reliability is then predicted from the strength distribution and actual loading data.
