本文主要研究三点弯曲情况下的变截面扩张夹层梁。建立了基于折线假设(Z字形理论)的梁的分析模型。考虑剪切效应的梁的最大挠度是解析确定的。此外，建立了梁的数值有限元模型(SolidWorks)。计算并比较了两种方法计算的算例梁的最大挠度。结果在表格中指定。(C)2019爱思唯尔有限公司。保留所有权利。
The paper is devoted to expanded-tapered sandwich beam under three-point bending. The analytical model of the beam based on the broken-line hypothesis (zig-zag theory) is developed. The maximum deflection of the beam with consideration of the shear effect is analytically determined. Moreover, a numerical FEM model (SolidWorks) of the beam is formulated. The maximum deflections of example beams with the use of two methods are calculated and compared. The results are specified in Tables. (C) 2019 Elsevier Ltd. All rights reserved.
