Analysis on the interfacial shear strength of fiber reinforced titanium matrix composites by shear lag method

Strengthening behavior in high content SiC nanowires reinforced Al composite

“…Therefore, several models have been proposed to predict the yield strength of the composites [22][23][24]. It has been found that the yield strengths of particulates and short whiskers (the aspect ratio is less than 5) reinforced metal matrix composites could be well calculated by the modified hear-lag model after taking into account the tensile transfer of the load from the matrix to the discontinuous reinforcement [25].…”

Interphase region effect on the biaxial yielding envelope of SiC fiber-reinforced Ti matrix composites

“…It is supposed that all displacement components within each sub-cell of the RVE vary linearly. 21,29,[32][33][34][35] Furthermore, it is supposed that applied normal stresses on the RVE do not induce shear stresses within the sub-cells. 21,29,[32][33][34][35]39 The traction boundary conditions on the RVE faces implying the balance of the RVE faces in normal directions between the applied global stresses (S l ) on the RVE faces and local stresses ij l (l ¼ x, y, z) within the corresponding face sub-cell ij are given by…”

“…Metal matrix composites (MMCs), specifically SiC fiber-reinforced Ti matrix composites, have been extensively used in space and automobile industries mainly due to their low density, high specific strength and stiffness as well as stability of properties at elevated service temperatures. 19,20 In addition to the interphase region, 21 another factor, which significantly affects the overall behavior of these materials, is relatively high state of thermal residual stress (TRS) within the SiC-Ti MMCs due to cool-down process from high fabrication temperature to room temperature. 22,23 It should be noted that the TRSs appear due to mismatch between the coefficients of thermal expansion (CTE) of the constituents of the MMCs.…”
