The presence of the micro-stress intensity factor K cro in Eqs. (9) is reflected via where A2 is given by the second of Eqs. (5). Displayed in Figs. 9, 10 and 11 are the micro-stress intensity factor in Eq. (10) as a function of the ratio h g when the applied shear is fixed at 10MPa. With fixed t2 t1 5 and t1 tm 1, 2, 3 and 4, Fig. 9 shows that Km* stays nearly constant for each ratio Ti T with increasing amplitude of K cro as the shear stress ratio Ti T is increased. The same conclusion can be...

To examine the effect of interface adhesion (or interphase) properties on CNT-reinforced composites, it is assumed the elastic modulus of the interphase in a reasonable range. The interface phase is considered to be isotropic, with the Young's modulus Es pEm, where P is a nondimensional coefficient. Using the parameters of CNTs and matrix as in Section 2.1, the longitudinal tensile moduli of composites reinforced by aligned CNTs with cr 0.1 are plotted in Fig. 8. As the value of p increases...

The obtained equilibrium configurations of dislocation lines when a strong misfit center exists (due the volumetric misfit) are presented in Figs. 8(a) and 8(b). These are obtained by varying the Peierls-Nabarro stress barrier when the applied stress is fixed. Similarly to Fig. 7, the dislocation lines are pinned by the misfit center but two equilibrium solutions can be found for each given materials misfit and applied stress. The first one shows the same trend as that in Fig. 7 but with...

The calculated additional GB resistance Ax at different strain amplitudes is listed in Table 3. It can be seen that Axas is also increased with increasing strain amplitude. From the analysis and calculations above, it seems that the existence of a GBAZ with a higher stress may be responsible for the increase in the cyclic saturation stress and the disappearance of the plateau region in the CSSC of the really grown bicrystal RB. 4. Effects of Crystallographic Orientations and Perpendicular GBs...
