摘要: MatLab具有强大的符号运算功能.以平面梁单元刚度矩阵为例,详细介绍MatLab在单元刚度矩阵推导中的具 体应用,编写了平面梁单元刚度符号运算程序,运算结果与手工推导完全一致,该方法可进一步推广到其它单元甚 至到更复杂非线性单元刚度矩阵推导中.

关键词: MatLab, 符号运算, 刚度矩阵, 推导

Abstract: MatLab has a strong symbolic operation function.With the example of stifness matrix of plane beam element,the application of deducing element stifness matrix is introduced in detail for the first time,and the symbolic operation procedure of plane beam element is developed,and the ope ration result is completely in accordance with the handicraft deduction.This method can further expand the application of deducing matrix to other elements even more complicated nonlinear element.

Key words: MatLab, symbolic operation, element stifness matrix, deduce
