Obtain the strain from the model analysis solution
5 views (last 30 days)
I did a model analysis by using PDE toolbox and obtained the solution (natural frequency; mode shape; mesh). However, I would like to get the strain from the result of the model analysis. I tried directly using the command "StrainRF=evaluateStrain(RF)", but it shows "Check for missing argument or incorrect argument data type in call to function 'evaluateStrain'." If there is any other method to get the strain from the model analysis result? I appreciate any assistance.

Strain is in response to a applied loading. Modal analysis is a eigenvalue problem. So you won't be able to calculate strain from modal analysis. You might want to apply loading and solve a static/dynamic problem.
