Abstract

In this work we derive formulas to compute effective torsion, extension, bending and shear stiffness coefficients for

-layered axisymmetric beams that take into account the coupling due to deformation between layers. Further, the contributions of this coupling are studied for the case of two- and three-layered circular cross-sections. Finally, we proceed to check the applicability of the results to a particular case of interest, that of unloaded endoscope shafts. For this purpose, we show the results of an experimental campaign carried out on the medical devices.

用解析和实验方法确定多层轴对称梁的有效刚度

在这项工作中，我们推导了计算n层轴对称梁的有效扭转，延伸，弯曲和剪切刚度系数的公式，考虑了层间变形引起的耦合。进一步，研究了两层和三层圆形截面的这种耦合的贡献。最后，我们继续检查结果的适用性，以一个特殊的情况下感兴趣的，卸载内窥镜轴。为此，我们展示了在医疗设备上进行的实验活动的结果。

期刊介绍： The International Journal of Solids and Structures has as its objective the publication and dissemination of original research in Mechanics of Solids and Structures as a field of Applied Science and Engineering. It fosters thus the exchange of ideas among workers in different parts of the world and also among workers who emphasize different aspects of the foundations and applications of the field. Standing as it does at the cross-roads of Materials Science, Life Sciences, Mathematics, Physics and Engineering Design, the Mechanics of Solids and Structures is experiencing considerable growth as a result of recent technological advances. The Journal, by providing an international medium of communication, is encouraging this growth and is encompassing all aspects of the field from the more classical problems of structural analysis to mechanics of solids continually interacting with other media and including fracture, flow, wave propagation, heat transfer, thermal effects in solids, optimum design methods, model analysis, structural topology and numerical techniques. Interest extends to both inorganic and organic solids and structures.
