摘要：
An equation solver is developed based on the Gaussian elimination scheme. The in-core space requirement is minimized by implementing three levels of partitioning of the degrees of freedom. The solver is further developed to analyze materially non-linear structures with localized plastic regions. The method proves efficient for the solution of large structural systems in computing environments with severe in-core space limitations. © 1979.
