Then a dynamic visualization software - - afterdraw , which aims at 2d elastic - plastic fem , is programmed . afterdraw is capable of drawing the deformation figures of material , the regions of plasticity and the regions of tension distributing figures , primary stress vector figures and primary strain vector figures . besides , atterdraw could realistically dynamically simulate the deformation of the whole process of construction 在此基礎(chǔ)上,研究了針對二維彈塑性有限元的動態(tài)可視化后處理軟件afterdraw , afterdraw能夠繪制基坑工程各步施工的結(jié)構(gòu)變形圖、塑性區(qū)和受拉破壞區(qū)分布圖、主應(yīng)力矢量圖和位移矢量圖, afterdraw還能夠逼真地動念模擬基坑工程整個施工過程變形情況。
Abstract : the fundamental of three - dimensional discrete element method is introduced , a practical example of landslide is simulated with the c program developed by the authors , and some reasonable results consistent to the existing data are obtained it can be concluded that the three - dimensional discrete element method is a suitable method to dynamically simulate landslide 文摘:介紹了三維離散單元法的基本原理,編制了相應(yīng)的c語言程序,并對具體的滑坡實例進行了模擬,發(fā)現(xiàn)計算結(jié)果與已有研究成果較為一致,表明三維離散單元法是一種可以動態(tài)模擬山地滑坡行為的比較適宜的數(shù)值方法。
