Abstract:
insures convergence of the iterations to the equilibrium equations solution by any mode of loading. For computation of the coefficients in the equilibrium equations, a version of the fictitious-domain method is proposed, which allows essentially treatment of rectangular and nonrectangular sections in the same way, and makes the presented approach easily programmable and readily adaptable to different sections. An additional procedure is suggested for analysis of more difficult cases, when the strain in the extreme compression fiber of the section is considered as a variable that is not specified in advance. Numerical examples are given.
