| Abstract: | MatLab has a strong symbolic operation function.With the example of stiffness matrix of plane beam element,the application of deducing element stiffness matrix is introduced in detail for the first time,and the symbolic operation procedure of plane beam element is developed,and the operation 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. |
