| Popis: | 95 A thin curved interphase of thickness t between two media is considered on the torsion problem of composite shafts. The interphase is modeled by a surface between the two neighboring media, and appropriate interface conditions on it are derived for the warping function and shear traction fields. The derivation makes use Taylor expansions for the fields and is correct to O(tN), where t denotes the thickness of the interphase. The purpose of this thesis is discuss the imperfect interfaces. Two kinds of imperfect interfaces are considered: one which models a thin interphase of low shear modulus and the other models a thin interphase of high shear modulus. In the former case, the traction on the interface is continuous but the axial warping displacement undergoes a discontinuity. In the latter case, the warping displacement at the interface is continuous but the axial shear traction undergoes a discontinuity. |
