When load exceeds the flow stress, materials willplastically deform under the interaction of several independent mechanisms, such as nucleation and propagationof dislocations, diffusional flow, and viscous flow.Representing the deformation of materials about therange of dominance of each of the mechanisms in a two-dimensional map has been pioneered by Frost and Ashby, which have already proven to be very useful for predicting new phenomena and for ch

“Combination and complement of stiffnessand compliance” is theessence of Chinese traditional Kung Fu (e.g. Tai Chi), it is also one of the most important strategy to maintain superior mechanical performances for natural biological organisms. Although transferring this nature’s
