Linear Elastic Principals and their angles.

Post by hauptmech » 11 Nov 2016, 07:30

Hi,

I'm using the principal strains and principal angles output and I'm curious if there is anyone out there that is using them directly as they are?

I have to manipulate them a bit (split the principal values 'vector' into scalars and convert the angles into a rotation matrix/direction vectors) to make them usable.

It occurs to me that there might be a visualization they are useful for as currently output that I don't know about?

As an addendum, I found that I could split the principal stress/strain vectors with an Exported Variable directive in the Solver section:

Code: Select all

  Exported Variable 1 = Principal Stress[Principal_Stress_1:1 Principal_Stress_2:1 Principal_Stress_3:1]
  Exported Variable 2 = Principal Strain[Principal_Strain_1:1 Principal_Strain_2:1 Principal_Strain_3:1]
