Micromechanical model of time-dependent damage and deformation behavior for an orthogonal 3D-woven SiC/SiC composite at elevated temperature in vacuum
2020, Journal of the European Ceramic SocietyEffect of porosity on the nonlinear and time-dependent behavior of Ceramic Matrix Composites
2020, Composites Part B: EngineeringCitation Excerpt :These are the industry preferred methods used to determine quality of as-manufactured parts since these techniques are relatively fast and inexpensive to perform in the field. Under external load, CMCs exhibit nonlinear stress-strain behavior due to development of matrix microcracks and fiber fracture [18]. At elevated temperatures, CMCs also exhibit permanent deformation under external load [19] due to creep of the constituents [34].
Strain field evolution of 2D needled C/SiC composites under tension
2017, Journal of the European Ceramic SocietyCitation Excerpt :Investigating the strain distribution can help to better understand the damage mechanisms of CMCs, which is important in the design and application of CMCs. Previous experimental work has been performed to investigate the tensile behaviors of CMCs and demonstrated that the resulting tensile responses are non-linear [5–9]. While all these previous studies were helpful in understanding the basic tensile behavior of CMCs, only averaged macroscopic tensile responses were achieved in these studies since traditional contact strain measuring techniques (e.g., strain gage measurement, extensometer measurement) were applied.
Deformation and damage modeling of ceramic matrix composites under multiaxial stresses
2016, Composites Part B: EngineeringCitation Excerpt :Such models have limited usefulness because they require ad hoc criteria to be used in situations involving non-monotonic and/or multiaxial loading. Based on extensive testing and observations by a number of researchers [3,4] it is now well established that the mechanism causing nonlinearity in the global stress-strain behavior of CMCs is progressive microcracking of the matrix and at or near fiber–matrix interfaces. A more detailed description of this progressive microcracking process can be found in Refs. [3] and [5].
Nonlinear vibration of matrix cracked laminated beams containing carbon nanotube reinforced composite layers in thermal environments
2015, Composite StructuresCitation Excerpt :Similar work for free vibrations of cracked FGM beams was performed by Ferezqi et al. [6] using the wave method based on Timoshenko beam theory. For cross-ply laminated beams, the transverse cracks may locate in the matrix with 90- plies [7,8]. There are several models to describe the matrix crack [9–18], in which the shear-lag model [9,12–18] is one of the effective approaches to solve the stress and strain fields in the interior of composites with matrix crack uniformly distributed throughout the length of beam.
