磨面分析表明, chme鋼基體高強度,高硬度、良好的強韌性配合和碳化物硬質點的彌散分佈,磨痕細短淺小,擠塑變形區細小均勻,抵抗沖擊滑動累積塑性疲勞能力強,是其耐磨性比zgmn13高的原因。The following conclusions are gained : ( 1 ) the located shear band prongs the ligament near the top crack tip and the structure may occur shear - mode fracture at the angle of 155 ? to crack when load is 87. 92mpa ; the mode of fracture of the flange joint structure is not possible to be void - mode ; ( 2 ) it is proved that loading and then unloading repeatedly can not increase the possibility of invalidation of the structure when the times of loading and unloading are not too more when load is operating pressure ; the structure is safe when the vessel is operating ; ( 3 ) in the fe model of the thesis, not considering the influence of water pressure test which is in the process of fabrication of vessel in fe results in larger deviation in analysi
得出了以下結論:在8792mpa的載荷下筒體一封頭連接結構處的集中剪切帶貫穿韌帶,可能發生沿與原裂紋線成155 「角方向剪切型斷裂;筒體一封頭連接結構不可能發生韌窩型斷裂; ( 2 )在工作壓力下進行次數不多的反復加、卸載,結構不會破壞,也不會喪失安定性:結構在工作狀態下是安全的; m在本文的彈塑性有限元模擬計算中,對于裂紋尖端進行力學分析時,不考慮壓力容器製造過程中水壓試驗的影響,將導致計算結果出現較大的偏差; ( 4 )筒體完全屈服時的載荷為92石3mpa ,封頭完全屈服時載荷為86The results show that small cr addition in steel can decrease the lamellar spacing of pearlite, and markedly increase strength and hardness with almost the same ductility and toughness, and accordingly improve wear and shelling - resistance of wheel steel
實驗結果顯示,加入微量的鉻,可以細化珠光體的片層間距,在保持韌塑性基本不變的情況下,顯著增加材料的強度和硬度,從而提高車輪鋼的耐磨性和抗剝離性能。Author thinks that the direction of the maximum plastic distortion along a constant radius around the crack tip may be considered as the direction of shear - mode fracture ( named pmax - criterion ) and the load when located shear band prongs the ligament in the front of crack tip is regarded as the limited load of shear - mode fracture. ( 3 ) the fad ( fracture assessment diagram ) of titled crack is proposed based on achievements of mesomechanics about i - ii complex ductile fracture of metal, and the titled crack is classified two kinds : void - mode fracture is assessed by fracture assessment curve, and shear - mode fracture by limited load. ( 4 ) using a fe program based on plantle - ressue theory to calculate some mesomechanical parameters, a flange joint structure of a high pressure vessel ( design pressure 31. 4mpa and the thickness of the hemispherical head is half of that of shell. ) is analyzed to determine whether the structure under operation pressure is safe or not, forecast the mode of potential invalidation and argue for the rationality of design of the structure
試件的整體斷裂為剪切型,但在試件芯部裂尖鈍化區中部出現了韌窩型啟裂並有一定的擴展,說明局部較高的應力三軸度也會使韌窩型機制得以發展,但是不改變試件整體的剪切型斷裂模式;對韌性斷裂的剪切模式的細觀機理做了一定的探討,並且提出了含裂紋構件剪切型斷裂的宏觀判據:認為裂紋前方的集中剪切帶中與裂紋尖端等半徑處最大有效塑性應變出現的方向可以作為裂紋剪切斷裂的方向(可簡稱為_ ( pmax )準則) ,集中剪切滑移帶貫穿裂紋前方承載韌帶時的載荷可以作為極限載荷;本文運用金屬韌性斷裂細觀力學在一復合型韌性斷裂方面的研究成果,採用失效評定圖的形式,提出了傾斜裂紋的安全性評定方法的基本框架。Toluene is a colorless liquid used as a solvent, formaldehyde helps harden nails and dibutyl phthalate is a plasticizer that makes nail polish flexible
