“…Schallamach, 1971;Anooshehpoor and Brune, 1999) and in simulations (Coker et al, 2003). There is evidence for slip pulses, on which attention is focused here, in the experiments of Mouwakeh et al (1991) and Tsai and Kim (1996). Figure 14 shows that the displacement distribution from a pulse train slip mode and from a crack-like slip mode are quite similar.…”

“…Tsai and Kim (1996) and Li et al (2002). In particular, Tsai and Kim (1996) observed three frictional sliding modes: steady sliding of the entire contact surface, stick-slip sliding of the entire contact surface, and sliding through the generation of concentrated sliding pulses. In one set of experiments, with sliding along the entire contact surface, the pullout force was steady for a low interface pressure and was oscillatory for a high interface pressure, analogous to the behavior in our calculations where a crack-like sliding mode occurs for low values of Σ 0 and a pulse-like mode for high values of Σ 0 .…”

Frictional sliding along an interface between two identical isotropic elastic plates under impact shear loading is investigated experimentally and numerically. The plates are held together by a compressive stress and one plate is subject to edge impact near the interface. The experiments exhibit both a crack-like and a pulse-like mode of sliding. Plane stress finite element calculations modeling the experimental configuration are carried out, with the interface characterized by a rate and state dependent frictional law. For low values of the initial compressive stress and impact velocity, sliding occurs in a crack-like mode. For higher values of the initial compressive stress and/or impact velocity, sliding takes place in a pulse-like mode. A variety of sliding modes are obtained in the calculations depending on the impact velocity, the initial compressive stress and the values of interface variables. One pulse-like mode involves well-separated pulses with the pulse amplitude increasing with propagation distance. Another pulse-like mode involves a pulse train of essentially constant amplitude. The propagation speed of the leading pulse (or of the tip of the crack-like sliding region) is near the longitudinal wave speed and never less than √ 2 times the shear wave speed. Supersonic trailing pulses are seen both experimentally and computationally. The trends in the calculations are compared with those seen in the experiments.

“…These assumptions are explained in detail in Gao and Li (2005), Nairn (1997). Since then, the shear lag idea has been widely applied to straight fiber pull-out analysis for different composite systems and has been further developed with various degrees of approximation (Cox 1952(Cox , 1990Gao and Li, 2005;Gao et al, 1988;Hsueh, 1992a;Kerans and Parthasarathy, 1991;Kharrat et al, 2006;Kim et al, 2004;Kim and Mai, 1998;Nairn, 1997;Nairn and Wagner, 1996;Rosen, 1964;Tsai and Kim, 1996;Wu and Davies, 2005;Wu and Yu, 1994). For example, some researchers assumed zero radial displacement and uniform matrix deformation confined in the cylinder geometry (Hsueh, 1988(Hsueh, , 1990Takaku and Arridge 1973).…”

“…crack propagation may starts from the fibre entry point E [8][9][10]. However, K-H Tsai et al observed that crack initiate at the fibre bonded end A during the fibre pull-out test [11,12]. In a rod pull out test that very similar to fibre pull-out test, C. Atkinson, et al observed crack initiation sometimes occur at point A and sometimes occur at Point E [13].…”

Abstract. Previous experimental studies of fibre pull-out test show two dangerous points on the interface. Failure usually occurs at the bonded end of the fibre (Point A) or at the entry point on the surface of the matrix (Point E). Both points have different singular stress fields which causes crack initiation, crack propagation, and final failure. In this paper, intensity of singular stress fields (ISSF) at the fibre bonded end A and ISSF at the intersection point E of the fibre and the surface are discussed. The analysis method focuses on calculating the finite element method (FEM) stress radio by using a reference model and an unknown model. In the unknown model and the reference model, same FEM mesh pattern is applied. To analyse the ISSF at A, the body force method solution is used as the reference model. To analyse the ISSF at E, the reciprocal work contour integral method (RWCIM) solution is used as the reference model. Then, the two ISSFs are compared and discussed by varying the fibre embedded length . When is shorter, the singular stress at A is larger than the singular stress at E. When is longer, the singular stress at E is larger than the ISSF at A.
