Abaqus traction test on cylinder strange displacement
Abaqus traction test on cylinder strange displacement
(OP)
Hi,
i imported from autocad a solid cylinder with diameter of 2.2 mm and lenght of 100 mm.
i meshed it using the C3D20R elements.
material:
i've applied an traction force on one extreme and fix all displacement on the other.
the problem is that the displacement field is strange.
i don't have only displacements along the extrusion axis but i have also transversal displacements.
the difference between the axial and transversal displacements is only of E-01.
i expected something like E-10 of difference.
is it normal?
i'm using abaqus 6.14
Some photo of model and displacements

Try to apply only a symmetry (XSYMM U1=UR2=UR3=0) in "encastre" section . Do not bloc u1, u2 and u3
