Hi.I just get access to abaqus.
Doing a small example case, a circular beam with both ends fixed, is subjected uniform load, I have tried many times, but the displacement is smaller than the theory, what could be the reason causing that?
Hi! It would be very useful if you give us some more specifications, about features of the geometry, magnitude of the load, material model etc. Did you check unit of measure in the material definition and in general consistency of them for the whole model?
A too coarse discretization of the geometry or a bad element type can cause a too stiff response. Try to use a finer mesh and select a suitable element type in order to avoid shear locking effects.
How much smaller? It could be the material you entered. Provide me with the material properties.
