摘要

我们研究了弹性非均质性对由不可压缩的功能分级新胡肯材料制成的实心圆柱体压缩的影响。假设剪切模量在轴向变化。考虑了固定-固定条件，即两个刚性压板固定在试样表面的两端。我们将平衡方程转化为常微分方程（ODE），并对其进行数值求解。在此基础上，我们研究了实心圆柱体的横向变形轮廓。此外，我们还计算了决定材料可能失效的 von-Mises 应力。

Effect of nonhomogeneity on compression of solid circular cylinders made of functionally graded incompressible neo-Hookean materials

We investigate the influence of elastic nonhomogeneity on compression of solid circular cylinders made of incompressible functionally graded neo-Hookean materials. The shear modulus is assumed varying in the axial direction. The fixed–fixed conditions are considered, i.e. two rigid platens are fixed to ends of sample surfaces. We transform the balance equations into ordinary differential equations (ODE) which are solved numerically. Based on, we investigate lateral deformed profiles of a solid circular cylinder. Furthermore, we compute von-Mises stress that governs the possible failure of the material.

期刊介绍： Meccanica focuses on the methodological framework shared by mechanical scientists when addressing theoretical or applied problems. Original papers address various aspects of mechanical and mathematical modeling, of solution, as well as of analysis of system behavior. The journal explores fundamental and applications issues in established areas of mechanics research as well as in emerging fields; contemporary research on general mechanics, solid and structural mechanics, fluid mechanics, and mechanics of machines; interdisciplinary fields between mechanics and other mathematical and engineering sciences; interaction of mechanics with dynamical systems, advanced materials, control and computation; electromechanics; biomechanics. Articles include full length papers; topical overviews; brief notes; discussions and comments on published papers; book reviews; and an international calendar of conferences. Meccanica, the official journal of the Italian Association of Theoretical and Applied Mechanics, was established in 1966.
