Hello, I am conducting my course research, and in it I will compare experimental results of tests on sandwich beams with FEA performed at Abaqus. as I don't have much experience with the software, for learning I decided to follow the steps used in this thesis: https://essay.utwente.nl/71376/1/Weijermars_MA_CTW...

I used PET material as a core, but my results are much lower than the author's.
Could someone help me with the reason for this?
My attempt file is attached here: https://gofile.io/d/dL92uV .
