Dear Peteroznewman,<\/p>\n
<\/p>\n
<\/p>\n
<\/p>\n
About “This is pushing and pulling on the top of the structure with larger oscillations of displacement. Why are you doing that?” , I want to do cyclic analysis to the structure following testing procedure from ATC and AISC until the material become plastic.<\/span><\/p>\n <\/p>\n “It is the worst idea for efficiently solving the deformation of the structure out to the limits of displacement.”, Any suggestions how do i know the structure displacement limit?<\/span><\/p>\n <\/p>\n “<\/span>A much better idea is to have a single step that goes out to 30 mm.”, I’m sorry but I don’t get what do you mean about this one.<\/span><\/p>\n <\/p>\n “<\/span>Perhaps you are trying to build up plastic strain. You don’t have the correct material model to accomplish that. You must use <\/span>Charboche<\/a>.” yes i was trying to do analysis until the structure become plastic not elastic anymore, and i will study about “Charboche”.<\/span><\/p>\n <\/p>\n Is there anything wrong in my model? I’m a newcomer to Ansys.<\/span><\/p>\n <\/p>\n Thank you Peter, your reply and suggestion are very helpful to my research and thesis.<\/span><\/p>\n","protected":false},"template":"","class_list":["post-95993","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
