以几何非线性余能原理为基础,通过对一悬臂曲梁自由端部受弯矩作用而产生大转动变形的数值算例分析,验证了该原理适用于解决具有曲线边界的几何非线性问题。%This paper is based on the geometric nonlinear complementary energy principle,with a numerical example of a cantilever curved beam which endured bending moment at the end of the beam was produced a large rotating deformation,the principle applying to settle the geometric nonlinear problem with curve boundary was demonstrated.
