double-yield surface model

基本解釋

The user material subroutine UMAT provided by the general software ABAQUS was used for programming for Shenzhujiang s double-yield surface model of earth rockfill materials.
利用ABAQUS提供的用戶材料子程序UMAT的二次開發(fā)平臺開發(fā)土石料的沈珠江雙屈服面模型，并以一面板堆石壩為例，結(jié)合ABAQUS的“單元增加/去除”技術(shù)進(jìn)行了壩體施工和水庫蓄水的仿真分析。
Deformation of preloaded soft ground was calculated with the Yin's double yield surface model, the viscoelastic-viscoplastic model and the viscoelastic-viscoplastic damage model respectively.
結(jié)合堆載預(yù)壓加固軟基實(shí)例，分別采用殷宗澤雙屈服面模型、粘彈-粘塑性和粘彈-粘塑性損傷模型進(jìn)行有限元分析。
