Solid particle erosion is an important reason of material failure in a number of engineering systems such as material transport pipe lines, coal liguefaction / gasificaion plants, thermal power plants, aircraft gas turbine engines
固體粒子沖蝕磨損在一些工程應用中是導致材料失效的重要原因，如物料輸送管道、煤液化氣化裝置、熱能裝置、航空器噴氣引擎、等。 -
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。 -
Then, the deformation of soil particle skeleton under the physical chemistry of electrical double ] ayer and exterior load are simulated, indicating the micro - mechanism of deformation, failure and creep for structural soil. because conventional constitute models are constructed according to reconstituted clays, not considering the structure in natural clays and structure damage course during loading, a elasto - viscoplastic damage model and the parameter determining method are put forward
針對過去用重塑土試驗建立的本構模型，沒能考慮天然土體中存在的結構性，沒有描述結構性土從天然原狀到加荷破壞的這一過程，建立了一個描述結構性土的彈粘塑損傷模型和參數確定方法。 -
Influence of interface characteristic on failure process and mechanical properties of brittle composite matrix with soft particle reinforcement
界面強度對柔顆粒增強復合材料破裂特性的影響 -
A finite element analysis ( fea ) was eventually conducted, using mori - tanaka model and j - integral, to further explain the toughening mechanisms and fracture behaviour of the particle interleaved composites. the aim of the analysis was to examine the influence of the particle concentration and size, and the interaction between the particle and the crack tip. fea results indicate that interlayer zones can effectively lower j - integral and stress around the crack tip, and the high stress distribution in the region close to the interface can be the driving force for interfacial failure
本文的最後還藉助于有限元方法對層間增韌復合材料進行了宏觀和細觀斷裂韌性分析，基於mori - tanaka等效夾雜理論，計算了顆粒含量和尺寸對j積分的影響，有限元分析的結果同樣表明層間增韌可以有效的降低裂紋尖端應力水平，並暗示界面是可能存在的失效原因，所進行的數值分析起到了進一步支持和解釋增韌機理的作用。 -
