摘要：	The journal article titled Multiscale Response of the Human Skull to Quasi-Static Compression (Alexander SL, Gunnarsson CA, Rafaels K, Weerasooriya T. Journal of the Mechanical Behavior of Biomedical Materials; 102, 2020) reported the nonlinear stress response of human skull bone to quasi-static compression. Power relationships were optimized to relate the local microstructure (bone volume fraction, or BVF) to the initial linear response (Youngs modulus) and subsequent failure stress at the microstructural level. These relationships were then used to calculate apparent macro-structural moduli at different scales for the initial regime before localized instabilities start to soften the material response. However, finite element simulations involving loading applied to the human head and predicting injury (skull fracture) require apparent stress-strain relations up to global failure. The present addendum derives this global stress-strain response up to final failure.
