Hi,

I s it possible to calculate loss factor of a material using comsol?

Thanks

Loss factor is a material property, which must be provided to the model from a datasheet or measurements.

use the PIM Method, you can calculate the loss factor

PIM (Power Input Method) is an experimental method for determining the loss factor, which as Edgar says, is a material property.

However, when using the PIM method you need to know the strain energy (or the kinetic energy) of the test object. For this purpose you can use a finite element model.
