NEUP CINR-18-15381: Multiaxial Failure Envelopes and Uncertainty Quantification of Nuclear-Grade SiCf/SiC Woven Ceramic Matrix Tubular Composites

The Direct Micromechanics Method will be used to determine constitutive relations and multiaxial failure envelopes of nuclear grade SiCf/SiC composite tubes. 2D and 3D woven composites with two weave architectures will be tested in a variety of loading configurations, strain rates and temperatures to develop multiaxial failure criteria and validate the failure envelopes. The variability in properties due to microstructural heterogeneity and uncertainty in failure envelopes will be quantified.
