Abstract

In this paper, thermoelastic stresses of a functionally graded annular rotating disc subjected to internal and external pressure has been studied. Elasticity modulus, thermal conductivity, coefficient of thermal expansion and density of the disc are presumed to vary radially in accordance with three distinct power-law functions and the Poisson's ratio remains constant. A gradient index parameter is opted among -0.5 and 0.5. When this parameter equals zero, the disc turns into an isotropic disc. The distributions of radial and tangential stresses on the disc are obtained for various gradient parameters.

具有径向变化特性的功能分级环形旋转盘的热弹性应力分析

本文研究了受内外压力作用的功能分级环形旋转盘的热弹性应力。假设圆盘的弹性模量、热导率、热膨胀系数和密度按照三个不同的幂律函数径向变化，泊松比保持不变。梯度指数参数在-0.5 和 0.5 之间选择。当该参数等于零时，圆盘变成各向同性圆盘。根据不同的梯度参数，可以得到圆盘上径向和切向应力的分布情况。

期刊介绍： The International Journal of Engineering Science is not limited to a specific aspect of science and engineering but is instead devoted to a wide range of subfields in the engineering sciences. While it encourages a broad spectrum of contribution in the engineering sciences, its core interest lies in issues concerning material modeling and response. Articles of interdisciplinary nature are particularly welcome. The primary goal of the new editors is to maintain high quality of publications. There will be a commitment to expediting the time taken for the publication of the papers. The articles that are sent for reviews will have names of the authors deleted with a view towards enhancing the objectivity and fairness of the review process. Articles that are devoted to the purely mathematical aspects without a discussion of the physical implications of the results or the consideration of specific examples are discouraged. Articles concerning material science should not be limited merely to a description and recording of observations but should contain theoretical or quantitative discussion of the results.
