| Abstract: | This paper points out the limitations of traditional strength design theory after analyzing the reasons and conditions for fragile split of low stress of the high -strength materials and the large engineering structural components,and then suggests the detailed preventive measures both in design and in technology for this kind of split when the high-strength materials are used and large engineering structural components are designed. |
