以退火纯铜及正火铝青铜在轴向拉伸下进行室温静、动态蠕变试验。
In this paper, creep tests were carried out on annealed pure copper and normalized bronze containing Al under static and cyclic tension at room temperature.
软岩洞室群的破坏是一个动态问题，因此本文提出了扰动蠕变的概念。
The failure of soft rock chamber is a dynamic problem. The new concept "disturbance creep" is proposed in the paper.
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.
