通过准静态试验测试了蜂窝铝夹芯板的局压力学性能,分析了其破坏过程、破坏形态和典型荷载-位移曲线,研究了面层厚度、孔棱大小、压头类型、边界条件等因素对其极限荷载和吸能能力的影响。结果表明,蜂窝铝夹芯板局压荷载-位移曲线表现两种典型类型,呈现出弹性阶段、局部损伤阶段、强化阶段、整体损伤阶段、压缩致密阶段、底部破坏阶段等六个主要阶段。面层厚度和孔棱大小对夹芯板局压承载力和吸能能力有一定影响,压头类型对局压承载力和刚度有较大影响,但对吸能能力影响不大,边界条件和试件厚度对夹芯板强度和吸能能力影响不大。
Quasi-static localized indentation tests were carried out to investigate the indentation mechanical properties of the aluminum honeycomb sandwich panels. The destruction process,failure behaviors and typical force-displacement curves were analyzed. The impact of surface plates thicknesses,aperture sizes,intender types and boundary conditions on the ultimate load and energy absorption capacity were studied. The results indicate that the aluminum honeycomb sandwich panels have two kinds of typical force-displacement curves,and six stages are presented: elastic stage,local destruction stage,intensify stage,entirely damage stage,compression density stage and bottom damage stage. Surface plates thickness and aperture size have certain influence on load bearing capability and energy absorption capacity. Indenter types have much influence on load bearing capability and rigidity,but little influence on the energy absorption capacity. Different boundary conditions and core thicknesses have less influence on strength and energy absorption capacity of aluminum honeycomb sandwich panels.
