文摘

Two schemes for buckling analysis of FGCP based on HSDT and CPT are provided. New displacement field based on traction free surface and neutral plane is offered. The proper adhesive functions for satisfying boundary conditions are proposed. A modified Euler–Lagrange equation based on CPT is obtained and then solved. The better results based on HSDT in comparison to other works are obtained.
