The results are pretty much close to that in literature. However, when I performed it with skin, modal frequencies appears much larger to that in literature. Actually, skin is made up of oralight sheet whose mass density is given with a value of 36 g\/m^2. However, I didn&#039;t find any option in material properties of ANSYS to enter mass density. So, I divided it by thickness of sheet which is 12 micro-meters and convert it into 3000 kg\/m^3 .
