Abstract

Abstract The aim of this work is to propose a sandwich beam with stepped layer thickness in three parts along its length. The total depth, width of the cross-section and its mass are constant. The beam is under a uniformly distributed load. The system of two equilibrium equations was formulated for each part based on the literature. This system was analytically solved for the successive parts of the beam and the functions of the shear effect and deflection were determined in them. The effective stepped layer thicknesses was determined on the basis of the adopted criterion for minimizing the maximum deflection of the beam. The example calculations were made for two elected beams. The effective shapes of these beams are shown in the figures. Moreover, FEM numerical calculations of the deflections of these beams are performed.

端部夹紧的阶梯夹层梁的有效成形

摘要本文的目的是提出一种沿其长度分三部分分层厚度的夹层梁。截面的总深度、宽度和质量都是恒定的。梁承受均布荷载。在文献的基础上，对每个部分分别建立了两个平衡方程的体系。该系统对梁的连续部分进行了解析求解，并确定了剪切效应和挠度的函数。根据梁的最大挠度最小准则确定了有效阶梯层厚度。对两个选定梁进行了算例计算。这些梁的有效形状如图所示。此外，还对这些梁的挠度进行了有限元数值计算。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
