| Abstract: | This paper,following a minimum potential principle,derived the formula calculating the critical loads of the elastic rectangular thin plate with holes and columns under various conditions.Nowadays,there is no formula for calculating the critical loads for the rectangular thin plats with holes and columns,but in actual engineering,there are many thin plates with holes and columns.The calculation of the critical load can be solved by this formula. |
