  1. In order to study the influence of evolvement of permeation character induced by mesoscopic structural characteristics on macroscopic mechanical behavior and fracture mechanism, a nonlinear constitutive equations describing the relationship between damage of rock and seepage is proposed based on mesoscopic damage mechanics and biot seepage mechanics theory and coupling system of flow & solid in rock failure process analysis, f - rfpa2d, is developed to simulate the variation of permeability as well as coupling mechanism between seepage and stress during the initiation, propagation and coalescence of cracks in rock. this study also extends the research field of original rfpa2d

    摘要短裂紋的萌生與擴展是一復雜的非線性動力學過程，短裂紋擴展速率具有非線性動力學系統的混沌現象和自組織特徵。
  3. 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。
  4.
