Extracting Modal Strain Energy

Is there a way to extract the strain energy from a particular mode shape? I know it is relative but that's OK. I am calculating the damping effect of viscoelastic materials on the assembly. I have modeled a Solidworks assembly with the structure in question and the viscoelastic material as a component in the assembly. The Modal Strain Energy technique involves calculating the ratio of the strain energy in the viscoelastic material to the total strain energy in the structure for a particular mode shape. I am able to calculate the strain energy ratio for a static analysis but not for a modal/frequency analysis.

I guess a work around would be: Can the displacements from a mode shape be used to constrain a static analysis?

Thanks
