Abstract

The buckling and vibration of laminated plates with various types of non-uniform compressive edge loads is analyzed. This problem requires that first the elasticity problem be considered to obtain the distribution of in-plane stresses, and after that, the buckling problem is solved. The method of solution is based on the R-functions theory and the variational Rayleigh-Ritz method. The results are compared with the results obtained by other authors to confirm the reliability of the method. The behavior of a complex form plate with a cutout has been investigated.

受非均匀分布的面内力作用的层压板的屈曲

摘要

分析了各种非均匀压边载荷作用下层合板的屈曲和振动。这个问题需要先考虑弹性问题，得到面内应力的分布，然后再求解屈曲问题。求解方法基于 R 函数理论和变分 Rayleigh-Ritz 方法。将结果与其他作者获得的结果进行比较，以确认该方法的可靠性。已经研究了带有切口的复杂模板的行为。
