侵徹作用 的英文怎麼說
中文拼音 [qīnchèzuòyòng]
侵徹作用
英文
penetration effect-
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 substance of problems in simulating the damage and failure processes of material under dynamic loading, such as impact and penetration, is that the mechanics model of material transfers from continuum to noncontinuum
