자동차용 고장력강 박판재의 동적/충격 인장강도에 관한 연구 = On dynamic/impact tensile strength characteristics of high tensile steels for automobile

다국어 초록 (Multilingual Abstract)

Recently. the use of very thin high tensile steels as structural member materials of automobiles has been increased. Also. it is well expected that high speed automobiles are likely subject to dynamic and impact loading. It is known that the strength characteristics of structural members under dynamic/impact loading is quite different from that under static or quasi-static loading. It is therefore very important to clarify strength characteristics of thin high tensile steels under dynamic/impact loading quantitatively and qualitatively so that the structural design of automobiles using such materials could' be efficiently undertaken. This paper, carries out a series of tensile tests on thin high tensile steel materials in dynamic/impact loading condition varying the loading speed. Based on the test results. the dynamic/impact characteristics of thin high tensile steels as use of structural materials of automobiles are investigated. The application of the existing formulations for evaluating the dynamic effects is discussed. The experimental data obtained are documented for future use.
