- W2366709726 abstract "A variable cross-section compression bar is an important structural member in an engineering structure.When the compression of the bar reaches its critical load,the whole structure will lost the stability.Thus it was studied that the analytical approach for stability of variable cross-section compression bars with a perturbation method.First,the perturbation method of particular importance in solving linear homogeneous differential equation of second order with variable coefficients was derived in detail.Then the analytical solution of the slightly bending differential equation of the variable cross-section compression bar was constructed by using the perturbation method.And the critical load of the variable cross-section compression bar with boundary constraints was obtained.Finally,as the numerical examples,the critical loads of variable cross-section compression bars were calculated,and the calculation result agreed well with the result recorded in other literatures.It is shown by several numerical examples that this method is simple and practicable,and owns good precision." @default.
