One solution scheme results in the nonsymmetric linear equations due to the Newton iteration, while the other leads to the symmetric linear systems due to the symmetrized stiffness strategies. To solve the resulting linear systems, the QMR and SQMR solver are employed in conjunction with nonsymmetric and symmetric MSSOR preconditioner, respectively. A simple footing example and a pile\u2010group example are used to assess the performance of the two solution schemes. Numerical results disclose that compared to the Newton iterative scheme, the symmetric stiffness schemes combined with adequate acceleration strategy may lead to a significant reduction in total computer runtime as well as in memory requirement, indicating that the accelerated symmetric stiffness method has considerable potential to be exploited to solve very large problems.<\/jats:p>","DOI":"10.1155\/2012\/352081","type":"journal-article","created":{"date-parts":[[2012,2,20]],"date-time":"2012-02-20T21:01:56Z","timestamp":1329771716000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Applications of Symmetric and Nonsymmetric MSSOR Preconditioners to Large\u2010Scale Biot\u2032s Consolidation Problems with Nonassociated Plasticity"],"prefix":"10.1155","volume":"2012","author":[{"given":"Xi","family":"Chen","sequence":"first","affiliation":[]},{"given":"Kok Kwang","family":"Phoon","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2012,2,20]]},"reference":[{"key":"e_1_2_7_1_2","first-page":"1","article-title":"The best of the 20th century: Editors name Top 10 Algorithms","volume":"33","author":"Cipra B.
