Hello together, in the Structural Mechanics Module User's Guide the equation for the elastic strain energy density can be found on page 407 (also attached). The equation inculudes a ":" between the sigma and dEpsilonel in the integral. What is the exact definition of this ":", because it can not be a fraction? Please provide an explanation. Yours sincerely, Max

Hi Max,
The colon (:) represents the double-dot tensor product (or double contraction). See the theory section about Linear Elastic Material in the theory chapter in the documentation for the Structural Mechanics Module.
Best regards,
Magnus
