Abstract: | In this paper, the expressions of both increment stiffness matrix and total quantum stiffness matrix in nonlinear analyses are derived in detail, and their relationship is discussed in mathematical meaning.
The results given in our paper will be of great importance to the analyses of nonlinear numerical and nonlinear stability in finite element methods. |
