    摘要:

    本文基于雙線性張力位移法則，運(yùn)用ABAQUS內(nèi)置內(nèi)聚力單元對(duì)鋯-鈦-鋼復(fù)合板的剪切試驗(yàn)進(jìn)行了有限元模擬，分析了界面斷裂過(guò)程的應(yīng)力分布特征，研究了內(nèi)聚力強(qiáng)度、斷裂能對(duì)于界面層損傷的影響，并驗(yàn)證了剪切強(qiáng)度預(yù)測(cè)公式的正確性。研究結(jié)果表明：內(nèi)聚力單元可以模擬復(fù)合板界面層的斷裂過(guò)程，且與剪切試驗(yàn)結(jié)果良好吻合；剪斷位移與內(nèi)聚力強(qiáng)度呈正相關(guān)；隨著斷裂能的增加，剪斷位移、特征位移和最大剪切力都增加；剪切強(qiáng)度預(yù)測(cè)公式可對(duì)不同熱處理工藝下剪切強(qiáng)度進(jìn)行預(yù)測(cè)。

    Abstract:

    Based on bilinear force displacement law, finite element simulation of shear force test on zirconium-titanium-steel clad plate was carried out by using cohesive zone unit of ABAQUS, then, the effect of cohesive strength and fracture energy on the damage of interface layer was studied. Also the correctness of the prediction formula of shear strength was verified. The results show that cohesive element can simulate the fracture process of clad plate interface layer and agree very well with the results of shear force tests. Shearing displacement and cohesive strength was positively correlated. With the increase of fracture energy, shearing displacement, characteristic displacement and maximum shear force increase. The fitting formula of shear strength can predict shear strength under different heat treatment.
