5 、循环荷载作用下,试件出现了正截面裂缝和斜截面裂缝。 - Research on quantification of different shape cross section cracks with pulsed eddy current nondestructive testing technology
脉冲涡流无损检测技术对不同截面形状裂纹的定量检测研究 - The main conclusions are as following : 1 . specimens have four kinds of fatigue failure characteristics such as normal section crack width and truncated section crack width beyond the limit , the fatigue damage of steel bars . specimens ’ fatigue life is from 15 thousand to 1800 thousand
主要结论如下: 1 、试件出现了正截面裂缝宽度达到限值、斜截面裂缝宽度达到限值、钢筋疲劳断裂等疲劳破坏特征,疲劳寿命介于1 . 5万次180万次。 - 2 ) through many numeral experiment , using the crack face ' s slant angle and azimuth angle as parameters , we found some relations between three - dimension fractal parameters and two - dimension fractal parameters in rock mass : ds = ( 1 . 0 + 0 . 031 ) * dl + ( 1 . 0 + 0 . 0395 ) , ns = nl , v = 1 . 5986 * ( 2 - dl ) - 3 . 2935 * sin ( st ) + 3 . 8263 , and found a way to speculate three - dimension fractal parameters from two - dimension fractal parameters . lt is the foundation to describe the distribution laws of crack face in rock mass by the observing results through rock mass section crack , 3 ) this paper constructed the three - dimensional fractal emulation theoretical system and erected three - dimensional fractal emulation model about crack face in rock mass 4 ) a emulation system about crack face in rock mass is developed by vc + + , it includes the function to get section plane chart and section block chart from three - dimensional network chart automatically , and some of the emulation examples is given
2 )通过大量数值试验，以岩体裂缝面的倾角与方位角为纽带，分析得出了岩体裂缝面数量三维分形分布参数和岩体裂缝迹线二维分形分布参数的关系： d _ s = ( 1 . 0 0 . 031 ) * d _ l + 1 . 0 0 . 0395 ， n _ s = * n _ 1 ， = 1 . 5986 * ( 2 - d _ l ) - 3 . 2935 * sin ( st ) + 3 . 8263并提出了由二维分形几何参数来推导三维分形几何参数的方法。为通过岩体剖面裂缝直接观测结果，描述岩体裂缝面分布规律奠定了基础。 3 )本文构建了岩体裂缝面的三维仿真理论体系，建立了岩太原理二大学周眨d二研究生学位论文体裂缝面的三维分形仿真模型。 - As soon as the normal section cracks , the crack firstly appears in the flexural region . at this moment , the load - deflection curve has a turning point . with the increase of the load , the rigidity of the beam decreases compared with that before cracking because of the development of cracks in flexural region , and the formation and development of diagonal cracks toward the loading point , the load - deflection curve is basically linear till the beam fails
正截面开裂前，荷载挠度曲线基本为线性，截面刚度较大；正截面开裂时，裂缝先在纯弯段出现，荷载挠度曲线出现转折点，随着荷载的增加，纯弯段正裂缝的发展以及剪跨段斜裂缝的产生并向梁的受压区加荷点发展，使梁的刚度较截面开裂前减少，荷载挠度曲线也基本为线性直到梁破坏。
