In the no nlinear numerical simulation of finite element for materials，components and structures，the load increment control method is usually powerless when it is necessary to reach or pass through the peak point and the softening decent segment of special equilibrium path for load-displacement relation. In this paper，a new theory of displacement control proposed by Du Xiuli et al. is used to overcome this problem. To make a new stiffness matrix symmetric and banded，the main diagonal elements of stiffness matrix in the conventional finite element incremental equation were multiplied by a huge number，and the boundary conditions were also introduced to the finite element equation. Therefore，only a little modification was needed for the program of traditional load control method which can simplify the iterative process of calculation. Finally，the complied program MATLAB was used to analyze some practical examples. It is shown by the analysis that the method presented in the paper is not only effective，feasible，but also simple.
