力学分析用于推导低密度材料的有效弹性模量。在各向同性介质的情况下，采用开孔和闭孔几何模型。五个独立的有效模量是针对低密度横向各向同性介质得出的。由弹性稳定性定义的压缩强度也可用于开孔和闭孔各向同性材料。将理论结果与一些实验结果进行了比较，并针对以前的工作进行了评估。
Mechanicsanalyses are used to derive the effective elastic moduli for low density materials. Both open cell and closed cell geometric models are employed in the case of isotropic media. The five independent effective moduli are derived for a low density transversely isotropic medium. Compressive strength, as defined by elastic stability, is also derived for open cell and closed cell isotropic materials. The theoretical results are compared with some experimental results, and also are assessed with respect to previous work.
