Effect of Influential Factors on the Reliability of the Mechanical Behavior of a Composite Plate Holes Fatigue Loaded

Abstract:

This work presents a sensitivity analysis of mechanical and geometrical parameters on a composite component under a cyclic loading. A design of experiments approach has been used. This study in improved by a reliability approach where the scatterings of all the characteristic properties are taken into account. The Monte Carlo method where used to compute the reliability. An application has been carried out on a composite rectangular plate with a hole in its center. Where a useful surface responses diagrams of the reliability are determined. A significant nonlinear effect of the fiber volume faction is observed on the behaviors reliability with no significant interactions effect with the others factors.
