Dear all,
I am using ABAQUS to perform the nonlinear buckling study of composites right now, I am also trying to use Virtual Crack Closure Technique(VCCT) to study the strain energy release rate. However,here I have some questions regarding to obtain the nodal force and nodal displacement.
1. Could anyone give me some ideas how to obtain nodal force in Abaqus?
2. Since I am doing a geometrically nonlinear analysis, there may be large deformation in the model, do I need to transform those nodal forces from global coordinate into local coordinate system or the nodal force values are already the values in local coordinate system?
Thank you in advance!
