Why is SEQV almost zero for this modal analysis of a cantilever beam in ANSYS 10.0?
It appears the component stresses are almost equal when the axial direction should be much higher.
This is an error in the modal expansion pass [Ref: Defect 40554.].
The stresses are being calculated using the plasticity curve in what should be a
linear stress pass. A workaround is to issue tbdele,all,all just before
doing the expansion pass.
