| heal.abstract | This study reports on the effects of axial thermal residual stresses, cyclic loading and presence of notches on the tensile performance of a SiC-fiber-reinforced barium-magnesium-alumina-silicate (BMAS) ceramic matrix composite. The residual stress state of the composite was experimentally measured by interrogation of the tensile curves at a uniquely well-defined common intersection point of unloading-reloading cycles in the tensile domain. Notch presence was critical on the material's mechanical response and promoted catastrophic failure shortly after the achievement of a saturated matrix crack state. The result of cyclic loading was an increase by 20% in sustainable stress throughout loading, as compared to pure tension. Scatter in elastic properties within specimens of different notch-to-width ratios was reconciled with theoretical expectations by application of a translation vector approach in the stress-strain plane, based on the material's residual stress state. Acoustic emission and infrared thermography provided valuable insight into damage identification, location and sequence. (C) 2012 Elsevier Ltd. All rights reserved. | en |
