ABAQUS PAPER's MATERIALLLLLLLLL

[kyhln]

I would like to create a model, which is impact modeling of a paper and steel ball. I did everything , but ball is jumping on paper and it is impossible. I know that material properties are wrong , and it is hard to find paper's properties. Are there anyone to tell me what is stress-strain of a paper ( normal copy papaer) and elasticity pls???????????????????????

 

[FEA way]

Young's modulus of paper is about 6 GPa. Poisson's ratio can be taken as 0,31. However keep in mind that paper is actually anisotropic (often treated as orthotropic), can be considered as viscoelastic and has negative Poisson's ratio in the thickness direction (so called auxeticity).

For this impact simulation you will also need some damage initiation and evolution criterion. It may be hard to find such properties for paper.
