对双层泡沫金属夹层梁在三点弯曲载荷作用下的破坏行为进行了实验研究和理论分析。观察到三种主要的失效模式，即压痕、面屈服和芯部剪切A-AB。此外，结合压痕和面屈服，和核心剪切和压痕，分别观察。给出了双层夹层梁在不同破坏模式下的临界破坏荷载的解析计算公式。分析结果与实验结果吻合较好。建立了双层泡沫金属夹层梁的破坏机理图，提出了双层泡沫金属夹层梁的最小质量设计方法。·对双层泡沫金属夹层梁在三点弯曲载荷作用下的破坏行为进行了实验研究和理论分析。·在实验中观察到三种主要的失效模式。·推导了双层夹层梁临界破坏荷载的解析公式。·分析结果与实验结果吻合较好。·建立了双层夹层梁的破坏机理图，提出了最小质量设计方法。
The failure behavior of the double-layer metal foam sandwich beam under three-point bending is investigated experimentally and analytically. Three main failure modes are observed, i.e. indentation, face yield and core shear A-AB. Also, the combined indentation and face yield, and core shear and indentation are observed, respectively. The analytical formulas are given to predict the critical failure loads of double-layer sandwich beams under different failure modes. Analytical results are in good agreement with the experimental ones. The failure mechanism maps of double-layer sandwich beams are constructed, and the minimum mass design of the double-layer metal foam sandwich beam is presented. • The failure behavior of the double-layer metal foam sandwich beam under three-point bending is investigated experimentally and analytically. • Three main failure modes are observed in experiments. • Analytical formulas are derived to predict the critical failure loads of double-layer sandwich beams. • Analytical results are in good agreement with the experimental ones. • The failure mechanism maps of double-layer sandwich beams are constructed, and the minimum mass design is presented.
