“…Thus, the thermal residual stress and strain can be calculated easily: ε r = −0.16%, σ r = −134.85 MPa, which correspond well with the experimental results obtained by Camus et al [5]. Hence, the monotonic tensile behavior of the ceramic matrix composite may be considered as damageable-elastic with respect to a fictitious thermalresidual-stress-free origin O' of the stress-strain axis.…”

-This paper outlines results from an experimental investigation on carbonaceous ceramic matrix composites (e.g., C/SiC) into mechanical behaviour under both monotonic tensile and step loadings, and into environmental behaviour exposed to oxidizing atmosphere containing oxygen. Complex damage phenomena like matrix microcracking, interficial debonding, fibre breakage and oxidation can occur in the serviced composites and result in progressive strain increase. These mechanisms can be modeled and formulated from the microscopic to macroscopic scales in order to predict damage development and final failure. The proposed models show good agreement with experiments and the ability to describe more complex damage procedure.

“…Therefore, the model accounts for this variation in intertow matrix void distribution, size, and shape as a mesoscale input parameter. Voids also exist within the intratow matrix cells and micrographs indicate that these voids are evenly dispersed and uniform in size (Camus, Guillaumat, and Baste, 1996;El Bouazzaoui, Baste, and Camus, 1996;Murthy, Gyekenyesi, and Mital, 2004;Sullivan et al, 2006). The meso-and microscale voids are accounted for at a length scale below that at which the matrix constituent (either at the meso-or microscale) is examined by analyzing a separate RUC and homogenizing the properties to provide higher length scale effective properties (Liu and Arnold, 2011).…”

“…The extreme stiffness, strength, and toughness, as well as nonbrittle failure of advanced CMCs make them an ideal choice over traditional materials for many aerospace applications, such as for components used in the hot section of turbine engines, rocket nozzles, and thermal protection systems (Inghels and Lamon, 1991;Camus, Guillaumat, and Baste, 1996;El Bouazzaoui, Baste, and Camus, 1996;Jacobsen and Brøndsted, 2001;Murthy, Gyekenyesi, and Mital, 2004;Aboudi, 2011;Goldberg, 2012;Goldsmith et al, 2014). Additionally, CMCs offer oxidation and creep resistance and thermal shock stability at elevated temperatures.…”

Advanced aerospace materials, including fiber reinforced polymer and ceramic matrix composites, are increasingly being used in critical and demanding applications, challenging the current damage prediction, detection, and quantification methodologies.Multiscale computational models offer key advantages over traditional analysis techniques and can provide the necessary capabilities for the development of a comprehensive virtual structural health monitoring (SHM) framework. Virtual SHM has the potential to drastically improve the design and analysis of aerospace components through coupling the complementary capabilities of models able to predict the initiation and propagation of damage under a wide range of loading and environmental scenarios, simulate interrogation methods for damage detection and quantification, and assess the health of a structure. A major component of the virtual SHM framework involves having micromechanics-based multiscale composite models that can provide the elastic,

Multi-scale models play an important role in capturing the nonlinear response of woven carbon fiber reinforced ceramic matrix composites. In plain weave carbon fiber/silicon carbon (C/SiC) composites, the carbon fibers and interphases will be oxidized at elevated temperature and the strength of the composite will be degraded when oxygen enters microcracks formed in the as-produced parts due to the mismatch in thermal properties between constituents. As a result of the oxidation on fiber surface, fiber shows a notch-like morphology. In this paper, the change rule of fiber notch depth is fitted by circular function. And a multiscale model based upon the change rule of fiber notch depth is developed to simulate the residual strength and post-oxidation stress-strain curves of the composite. The multi-scale model is able to accurately predict the residual strength and post-oxidation stress-strain curves of the composite. Besides, the simulated residual strength and post-oxidation stress-strain curves of 2D plain weave C/SiC composites in oxidation atmosphere show good agreements with experimental results. Furthermore, the oxidation time and temperature of the composite are investigated to show their influences upon the residual strength and post-oxidation stressstrain curves of plain weave C/SiC composites.
