Phase-field thermal buckling analysis for cracked functionally graded composite plates considering neutral surface

In this paper, the variational phase field model is adopted to analyze thermal buckling behavior of cracked functionally graded material (FGM) plates. Unlike existing works, the difference between neutral surface and mid-surface of FGM plates is taken into account in the present study. The kinematics of plate is based on first order shear deformation theory, while the crack is simulated by variational phase-field theory. The critical buckling...
