| 摘 要： | 采用能量法分析三边简支板在剪切荷载作用下的弹性屈曲性能,推导三边简支板格受剪下的临界屈曲应力计算公式。采用有限元方法进行均匀受剪三边简支板格弹性屈曲的数值验证计算。结果表明:当长细比大于1.5时,临界应力计算公式与有限元计算结果吻合较好。

| Abstract: | The elastic buckling of three simply supported edges plate under shear load is analyzed by energy method,and the calculation formula for critical buckling stress of three simply supported edges plate has been deduced.Numerical calculation has been carried out by FEA on the elastic buckling of three simply supported edges plate under uniform shear.It shows that the critical stress calculation formula matches the numerical results by FEA well when slenderness ratio is larger than 1.5. |
