摘要
通过在自行研制的摆锤式杆-杆型冲击拉伸试验装置上进行的 GFRP 材料的多冲试验,探讨经多冲后材料的本构关系与一次性冲击时本构关系的比较,并对其机理进行了初步分析.
An impact experiment of GFRP was made which included a repeated
multi-impact test on a low stress level and a single impact test on the
broken stress level.The comparison of these results and the preliminary
analysis of broken mechanism were given.Additionally,the transient tempe-
ratures of the specimen under impact were measured and the transformaion
of the energy was discussed as well.
