Abstract In this study, buckling analysis of cracked plates is performed by using peridynamics. A peridynamic Mindlin plate formulation is used and the numerical implementation is done using commercial finite element software, ANSYS. Critical buckling load is obtained by utilizing ANSYS Eigenvalue Buckling Analysis feature. Peridynamic results are compared against numerical and experimental results and a good agreement is obtained between different approaches. After verifying the formulation, it is utilised to investigate the effect of crack length, crack orientation and plate thickness on the critical buckling load values for a centrally and side-edge cracked plates subjected to clamped-free-clamped-free (CFCF) boundary conditions. Moreover, the effect of variable thickness on the critical buckling load is also examined.

使用近场动力学对裂纹板进行屈曲分析

摘要 本研究利用近场动力学对裂纹板进行屈曲分析。使用近场动力学 Mindlin 板公式，并使用商业有限元软件 ANSYS 进行数值实现。临界屈曲载荷是通过利用 ANSYS 特征值屈曲分析功能获得的。近场动力学结果与数值和实验结果进行了比较，并且在不同的方法之间获得了良好的一致性。在验证公式后，它被用来研究裂纹长度、裂纹方向和板厚度对中心和侧边裂纹板在无夹紧-自由夹紧 (CFCF) 边界条件下的临界屈曲载荷值的影响. 此外，还研究了可变厚度对临界屈曲载荷的影响。
