Use software like MATLAB or Python to plot deformation gradients. Seeing how a square turns into a rhomboid mathematically helps bridge the gap between theory and reality.
Since Part II emphasizes 3D stress states and energy methods, model the example problems in a simple Python script (using NumPy for tensor math) or an FEA tool like CalculiX or Ansys Student. Seeing the numerical solution validates the analytical solution.
: Explores behavior beyond the elastic limit, including engineering vs. true stress/strain, hardening, and friction block models to explain permanent deformation. University of Auckland 2. Essential Formulae for Reference In solid mechanics, the relationship between stress ( ), strain ( ), and displacement ( ) is governed by these fundamental equations: Equations of Motion (Equilibrium) For a 1D element, the balance of forces is given by: solid mechanics part ii kelly pdf
By mastering the contents of this document, you move from being a technician who applies formulas to an engineer who understands the why behind the safety factor.
