裂纹既是复合材料梁构件的主要损伤类型之一,也是构件失效的主要原因之一.材料产生裂纹时,由于内部能量分布的变化,对外显现的动态特性会发生明显变化.对健康构件试样和裂纹损伤试样进行了大量对比研究,找到了损伤状态下动态特性的特征分布,并以此为依据建立了裂纹损伤的诊断规则.

The dynamic mechanical behaviours of super low carbon high Mo austenitic stainless steel (00Cr20Nil8Mo6CuN)during hot deformation have been studied by using Formaster-Press hot working simulator. The hot deformation equation, as well as the relationship between peak strain, peak stress and Zener-Hollman parameter, together with the deformation activation energy have been resulted through the experiments.
