Mechanical Modeling of Transverse Constitutive Relationship of Yarns in Plain-woven SiC/SiC Composites at the Mesoscale
Source abstract
Abstract
The transverse constitutive relationship of warp yarns and weft yarns was established separately. A new analytical expression considering the coupling effect of fiber/matrix interface debonding damage was proposed to simulate the transverse elastic modulus of warp yarns. The validation using the finite element method shows that the analytical expression has good accuracy. The transverse cracking of single weft yarn and weft yarn attached to warp yarn was simulated with the finite element method, and the transverse constitutive relationship in these two cases was simulated. The transverse constitutive relationship of single weft yarn shows obvious brittleness, while the transverse constitutive relationship of weft yarn attached to warp yarn shows obvious toughness. The transverse constitutive relationship of warp yarns and weft yarns established in this paper can contribute to establish the three-dimensional constitutive relationship of yarns in the multi-scale modeling of the mechanical behavior of plain-woven ceramic matrix composites.
