FINITE ELEMENT ANALYSIS OF THREE-POINT BENDING MECHANICAL PROPERTIES FOR STAINLESS STEEL SANDWICH PANEL WITH CORE TUBES

College of Civil Engineering, Hunan University, Changsha 410082, China

摘要

摘要: 为探究新型不锈钢芯板三点弯曲力学性能，通过ABAQUS有限元软件进行数值模拟，研究不锈钢芯板的破坏形式及弯曲性能的影响因素。结果表明：不锈钢芯板在三点荷载作用下的弯曲曲线可分为弹性、弹塑性和破坏三个阶段；不锈钢芯板的主要失效模式可分为芯管端部剪切破坏、整体弯曲破坏和面板剪切破坏；板的三点弯曲极限承载力受面板厚度、芯管壁厚和芯管直径等因素影响。

Abstract: ABAQUS finite element software was used in numerical simulation to study the three-point bend properties of the stainless steel sandwich panel with core tubes, and explore the factors that influenced its failure mode and bending performance. The results showed that the bending curve of stainless steel sandwich panel under three-point load could be divided into three stages:elastic stage, elastoplastic stage and failure stage; and the main failure mode of stainless steel sandwich panel with core tubes was divided into shear failure at core tube end, the overall bending damage and the panel shear failure; the ultimate bearing capacity of the panel under three-point load was affected by the panel thickness, the wall thickness of the core tube and the diameter of the core tube.
