自适应多重网格有限元网格生成器研制 总被引:2,自引:0,他引:2
基于协调三角形剖分算法、分子表数据结构和Zienkiewicz-Zhu误估计方法,本文研制出适用于自适应多重网格有限元的网格生成器,该网格生成器可对复杂的区域进行自适应加密。当荷载作用边界随时间变及在动力荷载作用下,网格生成器可退化与再加密网格。 相似文献

Biot’s theory of consolidation of saturated soil regards the con-solidation process as a coupling problem between stress of elas-tic body and flow of fluid existing in pores.It can moreprecisely reflect the mechanism of consolidation than Terzhi-gi’s theory.In this article,we obtain the general Biot’sfinite element equations of consolidation with classical varia-tional principles.The equations have clear physical meaningand have been applied to analysing the consolidation of Bajia-zui earth dam.The computational results are in accord withengineering practice. 相似文献
