Damage and scatter behaviour of glass reinforced marine composite materials
Résumé
The present paper describes the extension to band layup glass fibre laminated marine composites of a model of behaviour previously developed for carbon reinforced plastics by Ladcvezc et al. (I}. It is based on damage mechanics applied at the elementary ply scale, namely on the description of matrix microcracking and fibre/matrix debonding. This study is restricted to unidirectional and cross-ply laminates. The emphasis is put on the identification methodology. The aims are to quantify elastic, damage and inelastic model parameters. Moreover, a statistical analysis is performed on the model elastic and damage parameters in order to justify the use of new mechanical characteristics.
