Firstly, the basic character of the remote filed eddy current is simulated and analyzed in case of two - dimension axial symmetry which approves the existence of remote filed eddy current phenomenon ; the full circumferential defect model is investigated to approve the feasibility of using the rfec techniques to detect the position and depth of defect ; the pit corrosion 、 circumferential and axial crack models are simulated, and the defect character based on voltage plane polar plot and the changes of phase and amplitude are analyzed to supply the standard for defect reconfiguration
首先，在二維軸對稱情況下模擬與分析了遠場渦流的基本特性，證實了遠場渦流現象的存在;對全周向缺陷的遠場渦流檢測進行了詳細研究，證實了遠場渦流檢測缺陷位置和深度的可行性;對點狀腐蝕、軸向與周向裂紋三種非軸對稱缺陷進行三維有限元模擬，利用相位差和幅值變化曲線與電壓平面極坐標圖對缺陷特徵進行分析，為缺陷形狀重構提供了依據。The proposed model - beam - particle model is validated to simulate some routine tests of concrete which including uniaxial compressive test and uniaxial tensile test to prove that the numerical model can effectively to describe the complete failure process caused by the initiation, propagation and coalescence of cracks. the influence of the meso - mechanical properties to the macroscopic failure behavior is discussed in this paper. the proposed model is employed to simulate the dynamic failure process of concrete under impact loading, and analyse the failure behavior of concrete with different impacting velocity
本文建立了混凝土的梁-顆粒數值模型，並利用該模型進行了混凝土在單軸壓縮和拉伸載荷作用下，混凝土從微裂紋的萌生、擴展、貫通直到宏觀裂紋產生導致破壞的全過程的數值模擬，探討了混凝土材料細觀結構對其宏觀力學行為的影響；利用該數值模型，模擬了鋼彈以一定的初始速率垂直侵徹混凝土圓板的動態過程，對計算結果進行了動畫顯示，並分析了不同鋼彈初始速率對混凝土圓板破壞形式的影響。The processes of propagation, kinking of micro cracks in concrete and the interaction among cracks as well as the induced failure are analyzed by using the model describing the wing type crack from the view point of micromechanics
摘要本文從混凝土細觀機理出發，採用翼型裂紋模型分析了圍壓荷載下混凝土內微裂紋擴展、彎折和相互作用直至材料破壞的過程。
