这些工作主要讨论了金属泡沫材料的拉伸、压缩、能量吸收、动态冲击、失效准则、本构关系、蠕变、疲劳和断裂等力学性能。
They are mainly concerned with the tensile and compressive behavior, energy absorption, dynamic impact, failure criterion and constitutive relation, creep, fatigue and fracture of these materials.
而以蠕变极限为失效准则的蠕变内应力法与常规的以蠕变试验为基础的等温外推法相比，还具有试验时间短的优点。
It is also shown that under the creep limit failure criterion, the creep internal stress method has the advantage of less test time in comparison with the isothermal...
