压力超载对X52管线钢无缝管疲劳裂纹扩展的影响

 中文X52管线管知识:试验研究了X52管线管裂纹扩展过程中超载载荷迟滞效应。在恒定的应力比下,在不同强度因子幅下通过计算X52管线管过载影响区大小来确定影响区内的迟滞裂纹扩展速率,并与无超载情况下的X52管线管裂纹扩展速率相比较,定性地说明X52管线钢裂纹扩展中的迟滞效应。
English X52 Seamless Knowledge: Study of X52 line pipe during the overload crack growth retardation effect of the load. In the constant stress ratio under different intensity factor amplitude calculated X52 line pipe through the overload affected zone size of the area to determine the impact of the crack growth rate retardation, and overloaded with cases without the X52 line pipe crack growth rate compared to the qualitative description of X52 pipeline steel in the crack growth retardation effect.。以上无缝钢管相关信息知识由天津市广泰德钢管销售有限公司专业提供,详情点击:www.tjgg002.com
