“…In other words, in the small deformation problem and the frame of linear viscoelasticity, the Laplace transform or Separation variable method is applicable. Note that the strain of the nucleated pore due to the interface debonding is denoted as e v , and the pore stress is denoted as p v , Chen et al (2008) has derived the expression of e v according to the separation variable method, that is,…”

“…Based on Eshelby's equivalent inclusion theory, a new meso-mechanical analysis method was adopted to investigate the partial debonding of inclusions (particles or fibers) (e.g. Chen et al, 2008Chen et al, , 2010Lee, 2000, 2001;Ju and Sun, 1999;Ju et al, 2006;Liu et al, 2004;Paulino et al, 2006Paulino et al, , 2008Sun and Ju, 2004;Sun et al, 2003Sun et al, , 2010Wong and Ait-Kadi, 1997;Zhao and Weng, 1997). Because the partially debonded inclusions could partially transverse stress, those inclusions could be approximately considered as anisotropic ones, and thus the Eshleby's theory is still valid for analyzing the overall mechanical properties of composites.…”

Interfacial debonding between fibers and matrix is one of the dominant damage types in fibrous composites. This paper investigates weakening effect due to the interfacial debonding. For simplification, the fibers are assumed to be rigid since the modulii and strength of fibers are much greater than those of matrix, and the distribution of the radii of fibers is assumed to obey the logarithmic normal distribution. The matrix is assumed to be a viscoelastic material. The boundary of the composite is subjected to transverse loading condition, the direction of which is perpendicular to that of fibers. The interfacial debonding between fibers and matrix is analyzed by the energy criterion, and the evolution formula of nucleated porosity due to the debonding is derived by the statistical approach. A newly defined volume average method is proposed to establish the macroscopic constitutive relation of the composites. The effect of the material parameters of matrix, as well as the size of fibers on the critical stress for the interfacial debonding and damage evolution are discussed in detail. The results obtained in this paper indicate that the macroscopic strain rate, the dispersion degree of the fiber's radii, the adhesive energy at the interface, and loading condition play key roles in the overall mechanical properties of the composites.

“…Though, the effective stress varies a little with particle size but the threshold, σ o , decreases from 19.83 MPa to 16.29 MPa with the increase in particle size from 1.7µm to 45.9 µm, Table 1. Under external load, as the deformation of material reaches to threshold value, the interfacial debonding occurs between particles (SiC p ) and the matrix (Al) (Chen et al 2008). Due to which the stress triaxiality in the matrix near the reinforcement will decrease and the debonded particles are no longer be able to transfer the stress.…”

The steady state creep in Al-SiC P composite cylinder subjected to internal pressure was investigated. The creep behavior of the material were described by threshold stress based creep law by assuming a stress exponent of 5. The effect of size and content of the reinforcement (SiC P ), and operating temperature on the stresses and strain rates in the composite cylinder were investigated. The stresses in the cylinder did not have significant variation with varying size and content of the reinforcement, and operating temperature. However, the tangential as well as radial strain rates in the cylinder could be reduced to a significant extent by decreasing size of SiC P , increasing the content of SiC P and decreasing operating temperature.
