hello dear all,<\/p>\n

<\/p>\n<\/p>\n

during the simulation of compression test with static structural, I got my result from Deisplaement force and then convert them to stress-strain. There is some differences between the elastic part and I do not know what causes this deviation.<\/p>\n

I am verifying my result with an article that they gave me this information about the analysis :<\/p>\n

Linear Isotropic Hardening, two rigid bodies up and down of flexible structure moving in quasi-static compression with the strain rate 0.01 mm\/s downward (upper plate is moving and the bottom plate is fixed)<\/p>\n

They said Ansys non-linear mechanical solver was used to solve the simulation but they did not mention they used explicit dynamic or static structural so I used static structural and i tried to mesh my structure with the element and node very close to their simulation. I have Density, Elastic modulus, and yield stress fo linear Isotropic hardening and I input all the data in the material section<\/p>\n

But finally, my result has deviation and how much oi tried to find the reason, I can not understand why there is different between them<\/p>\n

Anybody can help me ? or can give me any suggestion?<\/p>\n

If i do the analysis with explicit dynamic, may my result change?<\/p>\n

<\/p>\n<\/p>\n

If there is needed to put more about the setting please let me know I can put the image to give me more guidance.<\/p>\n

I put the any result for the stress-strain figure in comparison with the result from the paper below :<\/p>\n
