| 摘 要： | 夹芯结构具有质量轻、高比强度、比刚度、抗震性能好等优点,在航空航天、船舶、交通运输、建筑等行业都有着广泛的应用。在受到集中荷载作用时,夹芯结构易于产生较大的局部压入变形。本研究了夹芯板在点荷载作用下的结构响应,根据虚速度原理,得到压入载荷及结构变形随压头位移的变化关系。该研究成果可用于夹芯结构的结构设计,并为夹芯结构其它更为复杂的力学行为的研究提供参考。

| Abstract: | Sandwich structures have excellent properties, such as light weight, high specific strength, high specific rigidity and seis- mic resistance. These structures arc used widely in various industries, including aerospace, watercraft, transportation, construction etc. Subjected to concentrated loads, sandwich constructions are prone to cause more local indentation. In the paper, indentation response of sandwich panels under point load is analyzed, and relations of indenter load and structural deformation to indenter displacement are ob- tained based on principle of virtual velocity. Present achievement can be used for structural design of sandwich constructions, and. con- tribute reference to study on more complicated mechanical behavior of sandwich constructions. |
