SUMMARY
This discussion focuses on the concept of elasticity, specifically its formula ΔP/ΔV, which defines the relationship between pressure change and volume change. Participants noted that while elasticity typically refers to materials returning to their original shape, wood's heterogeneous and anisotropic properties limit its classification as elastic under all conditions. The conversation also highlighted the importance of the bulk modulus K in linear isotropic elasticity and the existence of more general elasticity forms for complex materials. Understanding these principles is crucial for accurately describing material behavior under stress.
