Linear Buckling Analyzing of Composite Sandwich panel

Linear Buckling Analyzing of Composite Sandwich panel

Linear Buckling Analyzing of Composite Sandwich panel

(OP)
I am new user of Abaqus and I have some doubts and I will thanks if anyone help me.
I am studying linear buckling behavior of composite sandwich panel which is composed of three layers. Namely GFRP laminates for the top and bottom surface and foam core for the core layer.
For the face sheet I am using isotropic material with the properties of (Ef(GPa)=30, vf=0.3, hf(mm)=0.1) and for the foam core I am using the orthotropic material with the properties of ( Ex(GPa)=4615, Ey(GPa)=46.1 vxy=0.25 and hc(mm)=0.8).

I am using Linear buckling analyzing which is modeled by plane stress, isotropic material for the face sheet and laminate for the core.

Question is that when I am doing the analyzing, the obtained results and buckling shape modes are completely different with the reference paper.

I am attaching the file and I will be thanks if anyone help me to solve this problem.
