Marc二次开发在混凝土徐变问题中的应用

Secondary development of Marc and its application to analysis of concrete creep

利用通用商业有限元软件Marc提供的用户子程序,对Marc进行了二次开发,将混凝土徐变的指数函数模型和混凝土弹性徐变方程的隐式解法引入Marc,实现了混凝土徐变问题的有限元求解,并在此基础上探讨了混凝土坝徐变应力的施工仿真问题在Marc中的实现,算例表明该方法是可行的.

By use of user subroutines, Marc is further developed. The exponential model of concrete creep and the implicit solution of concrete creep equation are introduced into Marc. The simulation of the construction of concrete dams in Marc is also discussed. The calculation of examples indicates that this approach is feasible.
