Shear strain/s for calculating shear modulus


I would like to calculate the change in shear modulus (shear modulus reduction) of a block element concerning the applied cyclic load. To achieve this, I plan to compute shear stress and strains for specific zones in the block.

After careful consideration, I am leaning towards using the SSmax command, which calculates the maximum shear stress based on principal stresses, for this analysis. However, I have some doubts when it comes to calculating shear strains.

Given that there are over 30 commands available for shear stresses and strains in 3DEC, I am uncertain which one would be the most suitable for my specific purpose. If you could kindly recommend a suitable command for calculating shear strains, I would greatly appreciate your guidance.

Thank you for your attention, and I look forward to your valuable assistance.

Best regards,
Vijay Kota
