屈曲

The first-order optimization algorithm was used to optimize and assess the updating parameters. The simulation analysis on an in-service rig derrick was carried out using the linear buckling, geometric nonlinear and double nonlinear methods.

以某型号在役钻机井架为例，利用该方法并结合线性屈曲法、几何非线性法、双重非线性法，对其进行了仿真建模和承载性能仿真分析，确定了该钻机井架的极限承载力、破坏形式及危险部位。

He recalled a child's voice, but the same tone, the same inflections...

他取消了孩子的声音，但是相同的明暗，相同的屈曲。。。

It is pointed out that the finite element analysis results are in good agreement with the Timoshenko classical solutions.

通过分析两铰圆管截面圆弧钢拱的平面外弹性屈曲性能，指出Timoshenko未考虑翘曲的经典解与有限元分析结果吻合很好。

All parameters of the criticalpoints of the Bernoulli-Euler beam and Timoshenko beam were derived.

分别把该准则应用于Bernoulli-Euler和Timoshenko梁的动态屈曲研究。

Finally,the buckling,bifurcation and stability of the Timoshenko beam is analyzed near the critical load through numerical calculation.

通过数值计算，分析了弹性Timoshenko梁在临界载荷处的屈曲和分叉以及稳定性，并与理论值进行了比较。
