Abstract

Piezoelectric semiconductors (PS) shell-like structures have great potential for the manufacture of innovative devices, such as nano sensors. To evaluate stability of such devices, a novel mechanical-electro-carrier (MEC) coupling PS cylindrical shell (PSCS) post-buckling model is developed based on the high-order shear deformation shell theory (HSDT). By applying the Galerkin technique in conjunction with newly developed trial functions, the mode-jumping equilibrium path, post-buckling deformation, distributions of electron concentration and electric potential are determined. The effects of crucial influencing parameters, including geometrical parameters, semiconductors constants and voltages on nonlinear stability of PSCS, are explored. Numerical findings reveal that, as a consequence of the MEC coupling effect, both the bifurcation point (first buckling) and load-bearing capacity of PSCS are reduced compared to those of classical piezoelectric counterpart.

一种新型机电载流子耦合压电半导体圆柱壳非线性稳定性模型

压电半导体（PS）类壳结构在制造纳米传感器等创新器件方面具有巨大的潜力。为了评估此类器件的稳定性，基于高阶剪切变形壳理论（HSDT）建立了一种新的机电载流子耦合PS圆柱壳（PSCS）后屈曲模型。利用伽辽金技术结合新开发的试函数，确定了跳模平衡路径、后屈曲变形、电子浓度分布和电势分布。探讨了几何参数、半导体常数和电压等关键影响参数对PSCS非线性稳定性的影响。数值结果表明，由于MEC耦合效应，PSCS的分岔点（首次屈曲）和承载能力都比经典压电材料有所降低。

期刊介绍： Thin-walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses. Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have contributed to this growth, and led to the need for a journal which concentrates specifically on structures in which problems arise due to the thinness of the walls. This field includes cold– formed sections, plate and shell structures, reinforced plastics structures and aluminium structures, and is of importance in many branches of engineering. The primary criterion for consideration of papers in Thin–Walled Structures is that they must be concerned with thin–walled structures or the basic problems inherent in thin–walled structures. Provided this criterion is satisfied no restriction is placed on the type of construction, material or field of application. Papers on theory, experiment, design, etc., are published and it is expected that many papers will contain aspects of all three.
