Hi
I am solving a problem ofmeasuring displacement in a thin plate (less than 1 mm in thick and 300 mm diameter) supportedat the annulus area (along entire circumference at a radius of 75 mm) mid way for 10 mm and rotated at 3000 r.p.m. The forces involved are only centrifugal and weight of plate.
Solving in 3D takes about a long time, so I am solving the problem as2D axisymmetric and I applied the weight and the centrifugal force simultaneously. But getting absurd results.
Is there a way by which I can apply the weight first and then using the results apply the centrifugal force to approach the problem in a realistic manner in 2D axisymmtric.
Also can I just include the centrifugal force in the load set or should I have to do some scaling.
