After pretension 0. 1 strain and pretorsion to 14, whereas the strength limit keep on increasing in company with the pretorsional capacity
其中屈服極限在預拉伸應變0 . 1后再預扭轉14后達到最大值,而強度極限隨著預扭轉量的提高不斷增大。Ltd. a coupled vibration method on suspended free poles is employed to determine the initial young ' s modulus at elevated temperatures, also the thermal expansion coefficients of fire - resistant steel
通過高溫下的恆溫加載拉伸試驗,得到不同溫度下耐火鋼的屈服強度、極限強度、延伸率、面縮率和應力應變關系,並測定高溫下耐火鋼的熱膨脹系數,採用懸絲耦合共振法測定高溫下耐火鋼的初始彈性模量。After pretorsion the successor tensile yield limit and strength limit both improved very highly, but the trend of the increase of the strength limit was suspended till the pretorsional capacity reached 17, when the pretorsional capacity was greater than17 ( prestrain value was 81. 19 % of total strain ), the successor strength limit rapid failed and approached the yield limit. this illustrate the a3 steel specimen translate from plasticity into friability after pretorsion strengthen. when the specimen was operated by tension - torsion action, the yield limit had very large improved, but the strength limit changed very little. furthermore, the trend of the increase of the strength limit was suspended till the pretension capacity reached 0. 25 ( prestrain value was 66. 93 % of total strain )
A3鋼試件在預扭轉后,后繼拉伸屈服極限和強度極限均有很大提高,但強度極限的增大趨勢到預扭轉量為17為止,預扭轉量大於17 (預應變值為總應變的81 . 19 )后強度極限迅速下降,與其屈服極限接近,這說明a3鋼試件經預扭轉強化后逐漸由塑性轉化為脆性。該預應變值為a3鋼試件的韌脆轉變點。 a3鋼試件在拉伸-扭轉作用下,屈服極限有很大提高,但強度極限沒有多大改變,而且,屈服極限的增大趨勢到預拉伸量為0 . 25應變(預應變量為總應變量的66 . 93 )后就不再增加。Comparing with these several strengthen formal, towards strength limit ' s improvement, the effect of torsion - tension and tension - torsion - tension was close ; simply tension - torsion - tension required a little larger prestrain quantity. whereas, towards yield limit " s improvement, the effect of torsion - tension - tension action ' s strengthen was the best
從幾種硬化形式的比較來看,對于強度極限的提高,扭轉-拉伸和拉伸-扭轉-拉伸的強化效果相近,只是拉伸-扭轉-拉伸所需的預應變量要大一些;而對于屈服極限的提高,扭轉-拉伸-拉伸作用下的強化效果最佳。When the a3 steel specimen was operated by tension - torsion - tension action, both the yield limit and strength limit had very large improved compared with that of monotonic tension. the improve scope of the yield limit could be 109. 36 %, the strength limit could be 56. 26 %. the yield limit value reached the max
A3鋼試件在拉伸-扭轉-拉伸作用下的力學性能與單一拉伸相比,試件的屈服極限和強度極限都有很大提高。屈服極限提高幅度最高可達109 . 36 ,強度極限提高幅度最高可達56 . 26 。分享友人
