  1. Finite element of dynamical bond stress of insert rebar under explosive loads

    爆炸荷載作用下植筋粘結應力有限元分析
  2. This paper focuses on the research of the stress mechanism of the ribbed shell structure in statics, dynamics and under the explosive load on the basis of the engineering practice of cave depot of single aircraft. in this paper, according to the classical shell theories, the basic differential equilibrium of the ribbed shell structure and the finite element analysis of 3d rippled plate are established, in which the function of annular ribs reinforcement bars and 3d ripped steel plates are distributed in the range of the steel, and the functions along the longitude direction of tension, bending, and torsion are neglected ; applied with dynamic analytical theory, the dynamic model of ribbed shell structure and the analytical theory model of elastic - plastic are set up ; the triangle series method is used to solve the displacement and stress under the distributed load and the concentrated load of the ribbed shell structure

    本文以軍用機場地面單機掩蔽庫工程建設為工程背景,首次對內襯三維波紋鋼板混凝土拱型復合結構的受力機理進行了靜力、動力和爆炸荷載的分析研究。根據將橫肋、鋼筋及三維波紋鋼板的作用均勻分佈在殼體范圍內的情況,忽略橫肋、鋼筋及三維波紋鋼板沿殼體母線方向的抗拉、抗彎及其抗扭作用,首次推導出了內襯三維波紋鋼板混凝土殼體的微分平衡方程,建立了有限元計算模型,並採用三角函數法,求解了三維波紋鋼板混凝土拱型復合結構在分佈荷載和集中荷載作用下的位移響應和應力響應,並與普通殼體進行了比較。
  3. The explosive welding specimen were also annealed in vacuum at various elevated temperature from 1000 to 1300. optic microscope, sem, tem and eds ( electron diffraction scattering ) techniques are applied to observe the microstructure and the element profiles of the welding interface and the interdiffused layer, reveal the interdiffused performance of alloy elements at elevated temperature, and analyze the structure and composition of the precipitated phases. moreover, the tensile strength of welding line with the two different techniques and various welding parameters were carried out

    採用金相、掃描電鏡、透射電鏡、能譜等多種實驗手段對焊接結合層的微觀組織結構、高溫下nb - 1zr與不銹鋼合金元素的互擴散行為,形成的互擴散層的成分、金相組織和擴散層中的析出相的相組成和相結構等,都進行了較為詳細的分析,並且對在不同工藝、不同焊接參數下焊接的nb - 1zr合金和不銹鋼的焊縫做了強度實驗研究。
  4. This paper using ls - dyna finite element analysis program to model the damage process of oilcan steel plate under no. 3 rock explosive load, analysing the effect of the mass and shape of explosive to steel plates extent of damage and shape of crevasse

    利用ls - dyna有限元程序,模擬了油罐鋼板在3 (上標# )巖石炸藥爆炸載荷下的破壞過程,分析了炸藥質量、藥柱形狀對鋼板破壞程度和破口形狀的影響。
