【摘要】 MATLAB作为一种强大的科学计算软件,自身又可以作为程序设计语言使用。本文结合地下结构静力和动力有限元分析中的一些问题,阐述了MATLAB在矩阵运算、求解自振频率以及有限元后处理中的一些技巧。文中分别提供了在直角坐标系和极坐标系下带有孔洞的平面问题的解决方案,并提供等值线和云图,供专业人员参考。更多还原

【Abstract】 As a powerful numerical computation soft, the MATLAB works well in programming as well。 The paper presents some skills in the finite element analysis of underground structures, especially in matrix operation,natural frequency of vibration,and post-processing of numerical values。Finally,the paper offers two programs for some special problems in the rectangular coordinate system and the polar coordinate system respectively。更多还原
