I am trying to make a dynamic random analysis, I defined a plastic material (standard PP). I defined a modal analysis with 8 modes also i defined four points for constrains completed fixed.
To define a random analysis i have some questions, if some have experience with this kind of analysis appreciate your help,
Actually i have made and analysis but I don´t know if that is right.
if i use the 3 rms the value is 365.4 psi which is bellow of 4351.13 psi of my current material, so this example is right or wrong.
Finally I made this analysis with linear properties, first i have trying to make it with non-linear properties but always send me a error message.
It seems to me that your is slightly densely 906 [kg/mm ^ 3], normally it should be 1.35 [gr/cm ^ 3] and to Simulate 1.35 * 10 ^-9 [t/mm ^ 3].
