AN APPROXIMATE CALCULATION FORMULA FOR SOWING THE LARGEST DEFLECTION OF A BUCKLING ROD

摘要

摘要: 利用特殊函数公式，得到第一类全椭圆积分在ρ→１时的近似展开，然后将近似展开式应用于屈曲杆问题，得到求解屈曲杆最大挑度的近似公式．该公式优于已有的屈曲籽大挠度的近似公式．

Abstract: in this paper,an approximate calculationformula for solving the largest deflection of a buckling rod is given by using the expansion formula ofelliptic integral of first kind. The formula has manyadvantages over existing ones.
