连续胶体材料化学-力学耦合有限元理论及其在ABAQUS中UEL程序实现
Finite element theory of chemo-mechanical coupling and the program implementation of UEL in ABAQUS for the continuous colloidal material
摘要
Abstract
Based on Hamilton’s principle,the equivalent integral forms of chemo-mechanical coupling governing equations and corresponding finite element forms are obtained.The strain matrix and element stiffness matrix represented by shape functions in chemo-mechanical coupling are derived in the global coordinate system.Discrete forms of element stiffness matrix are acquired in the local coordinate system. The user element subroutine UEL is programmed in ABAQUS finite element package.The numerical example shows the validity of the UEL developed,which can provide some references for the program-ming realization of UEL in ABAQUS software for various coupling problems with the form of the finite element.关键词
