Damage during uniaxial creep of a 2D Al(2)O(3)/SiC composite
The aim of this study is to analyse the uniaxial tensile and creep behaviour of an alumina fibre-reinforced silicon carbide matrix composite. The tensile behaviour is elastic-damageable and is related to the extension of fibre-matrix debonding which follows matrix cracking. The uniaxial creep of the composite is characterised by the occurrence of one or two tertiary stages. The first relates to progressive fibre-matrix debonding following matrix cracking which develops during loading. The second tertiary stage appears only at low creep stresses and is related to successive alumina fibre failure leading to non-catastrophic rupture of the composite. The study shows that a conventional Norton analysis of creep can only be considered by taking into account the damage state of the composite at the secondary stage.
