initially use a circular plate of 10 cm dia and 2cm thickness . Fix the circumference of the plate and apply a sinusoidal load like 1000*sin(10*time) in lateral direction in mechanical apdl. than plot the frequency , stress and potential graph.
use the density of material as 7500 kg/m3
and as the material is anisotropic use the stiffness matrix given in the document file.
in the stiffness matrix given in doc file multiply every row and column by 10^10 as it is given after dividing by 10^10. Like in the first row and first column take 13.2*10^10 instead of 13.2
