Transversely isotropic elastic moduli of a composite with partial particle debonding
- Rutgers Univ., New Brunswick, NJ (United States)
A theoretical principle is developed to determine the transversely isotropic effective moduli of a composite containing homogeneously dispersed, elastic spherical inclusions which, under the action of external tension, experience debonding on the top and bottom of the interface. The theory is developed on the assumption that the inclusions can no longer carry stress in the loading direction after debonding, but are still capable of doing so in the transverse direction. The effective moduli are then calculated as a function of volume concentrations of still perfectly bonded particles and already debonded particles, in addition to the properties of the inclusions and matrix. Comparison is provided between this newly developed theory and those of Mochida, Taya and Obata for partial debonding of rigid inclusions, and of Tohgo and Weng for complete debonding of elastic inclusions. It is found that the longitudinal Young`s modulus with partially debonded elastic particles always lies between these two.
