Study on micro - mixing in a rotating packed bed using the coalescence and re - dispersion model
用聚並分散模型研究旋轉填充床中微觀混合過程 -
Based on a large numbers of model / simulation test of the intermittent cracked rock - like samples, fatigue strength, fatigue deformation and crack appear in preexisting cracks tips, the growth of crack, the pattern of crack coalescence are studied / analysed systemically by means of cyclic load and static load, in the course of the model test, the difference between cyclic load and static load of crack appear in preexisting cracks tips, the growth of crack and the pattern of crack coalescence are observed and analysed
在試驗過程中，觀察並分析了循環加載方式下，預置裂隙端部裂紋萌生、擴展、巖橋貫通模式與靜載方式下的差異；探討了疲勞裂紋萌生、擴展的機理，分析了加載頻率、荷載水平對裂隙試樣疲勞強度、疲勞變形（總變形和不可逆變形）的影響規律。 -
One is void - model fracture which is resulted from initial, dilatation and coalescence of voids in material. the fracture criterion of void - model fracture is vgc - criterion or ctodi - criterion, and its fracture angle is able to be determined by m - criterion
韌窩型斷裂由材料內空穴的形核、擴張和匯合造成，斷裂判據可以採用「 v _ （ gc ）準則」或ctod ~ i準則，斷裂角可以採用m準則確定。 -
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。
