“…The creep behavior of the creeping matrix was predicted using a creep exponential law. Moreover, various investigators have studied fibrous composites by employing imaginary fiber method and technique (fictitious fiber) elastically [14][15][16][17][18].…”

This chapter presents a useful literature reviews and applied solved problems that focus on the creep phenomenon and behavior of it in the solids. Various insights and available studies are reviewed and investigated regarding the creep behavior analysis in three categories such as analytical, numerical and experimental methods. In addition, novel and recent findings are presented in this chapter such as predicting and obtaining the viscosity of the solids at high temperatures using steady state creep phenomenon (i.e., introducing a simulation and analogy between creeping solids and viscous fluids).

“…Modifications of the classical shearlag model have been made to obtain improved results (Hsueh, 1992;McCartney, 1989;Nairn, 1997Nairn, , 2004Nayfeh and Abdelrahman, 1998). Extensions of the shear-lag model with introducing interfacial friction have been proposed to analyse interfacial debonding during the fibre pull-out or push-out (Budiansky et al, 1986;Leung and Li, 1991;McCartney, 1989;Shetty, 1988;Zhou et al, 1993).…”

“…In this paper, we use a simple shear-lag mode with the focus on analysing the stress distribution and damage evolution in the cohesive fibre-matrix interface during the fibre pull-out. So compressive stresses on the fibre duo to matrix shrinkage (Gao et al, 1988), friction in the debonded interface (Budiansky et al, 1986;Hutchinson and Jensen, 1990;Leung and Li, 1991;Marshall et al, 1985;Shetty, 1988;Zhou et al, 1993), matrix cracking (Budiansky et al, 1986;Marshall et al, 1985), or fibre breaking (Chen et al, 2010;Nayfeh and Abdelrahman, 1998) are not considered.…”

“…The property of load transfer between the fiber and matrix components in fibrous composites has continued to receive vigorous attention of research in recent years. [1][2][3][4] However, the research productions of elastomer matrix composite with viscoelastic interphase have not been made public. In this paper, a micromechanical model of stress distribution and transfer in elastomer matrix composite with viscoelastic interphase was put forward.…”

A micromechanical model of short-fiber-reinforced elastomer matrix composite (SFRE) including the fiber, matrix and fiber-matrix interphase was established, in which main microstructural parameters, such as short fiber aspect radio, volume content and mechanic performances of main components, were taken into consideration, and the interphase was regard as a time-dependent viscoelastic component. The micromechanical stress transfer among short fiber, matrix and fiber-matrix interphase was studied. The equations expressing time-dependent tensile stress distribution on the fiber and the time-dependent shear stress distribution in the matrix and interphase were derived, and they were solved at the time t = 0 and t = + . A calculated example was carried out and the calculation results indicated that there existed the maximum fiber tensile stresses f (z, 0) and f (z, + ) at the fiber midpoint and both f (z, 0) and f (z, + ) equaled to zero at the fiber end, but the interphase shear stresses if (z, 0) and if (z, + ) reached to the maximum at the fiber end, and they equaled zero at the fiber midpoint.
