| Abstract: | Based on the theory of the finite element method of lines,a middle?thick bending plate on two?parameter elastic foundation is studied in the paper The variation of the potential energy functional of the platesfoundation system is obtained;then the equation of a bending plate is derived At same time,a program is developed to solve the bending plate The computing results are well agreed with that of the data from other references It will be seen from this that a new semi?analytical numerical method is proposed to solve such kind of problems |
