Improving Stability in the Time-stepping Analysis of Structural Nonlinear Dynamics
|Published in:||International Journal of Structural Stability and Dynamics, June 2008, n. 2, v. 8|
A change in the representation of discrete motion equations for nonlinear structural dynamics of two-dimensional bodies is developed. The objective is to write the motion equation in a less nonlinear form. This leads to a significant increase in the range of stability of the time integration process and a reduction in the number of Newton iterations required in the time integration step.
