Greetings,<\/div>\n
 <\/div>\n
I’m working on a project focused on analyzing the quasi-static compression behavior of Miura-ori structures made from paperboard. Initially, I planned to use LS-DYNA for this research. However, before diving into that, I decided to compare different solvers—static, explicit dynamic, and LS-DYNA—on a simple composite plate.<\/div>\n
 <\/div>\n
I followed a YouTube tutorial (https:\/\/www.youtube.com\/watch?v=z9NrKGGs9_o&t=458s) and found that when I used the static structural solver, my results matched the video perfectly. However, when I tried the same with LS-DYNA and the explicit solver, my results and deformation behavior didn’t align with the video. (The only difference in the models are in static structural there is nodal ratation boundary condition, whereas, since there is not such BC, I defined my rotation constraint as fixed rotation in explicit dynamics and LS-Dyna analysis)<\/div>\n
 <\/div>\n
I’m currently investigating the cause of this discrepancy. Could it be that the ACP module isn’t transferring data correctly to the explicit dynamic and LS-DYNA solvers? Here’s a quick summary of my modeling process and results:<\/div>\n
 <\/div>\n
 <\/div>\n
Any insights would be greatly appreciated.<\/div>\n
 <\/div>\n
Warm regards,<\/div>\n
