Isi artikel

A new method to analyze the wrinkling failure of anisotropic sandwich panels was discussed, for both symmetrical and asymmetrical wrinkling. To calculate the wrinkling loads, both shear and transverse normal modulus of the core were included in the analysis. First, the total energy of the system was calculated, and then using the Rayleigh-Ritz method, the exigent-system was solved to get the critical buckling loads. The results show that wrinkling could occur far below their corresponding Euler loads, that make them more dangerous. Wrinkling also contain shorter waves, that may lead to catastrophic failures. The results also show that the new method presented in this article is so general and can be used to calculate both Euler buckling and wrinkling loads of anisotropic sandwich panels simultaneously.
