摘要
针对结构和材料变形模拟中模型与原型间相互关系的特点，给出了亚耦联系统的定义、差功原理、位移亚耦联系统的变分原理．
Aiming at the special relation between model and original body in the simulation of construction and material deformation, this paper presents the sub-coupled systems conception, different work principle and variational principle of sub-coupled system in elasticity, the result of the peripheric fixed circular plate problem is given by the displacement variational priciple of sub-coupled system in elasticity.
