Small-strain kinematics
Understand the `Small-strain kinematics` governing equation when choosing an objective optimization for Structural Mechanics.
This relationship describes part of the physical problem being optimized:
\boldsymbol{\varepsilon}=\tfrac12\!\left(\nabla\mathbf u+\nabla\mathbf u^{\mathsf T}\right)
Check the variables, signs and units against your intended model. The objective and constraints must use quantities available in the selected study; this equation page does not create a separate editable model feature.
