Abstract :
Based on the Neumann serials and epsilon algorithm, an adaptive static reanalysis method for structural modifications is presented. In this process, the basis vector is formed using Neumann serials and an error-controlled evaluation epsilon algorithm is introduced to accelerate the convergence of the partial sum of the basis vectors. The present method significantly improves the convergence of the solution and maintains the quality of the results.
