Description
This lecture covers the concept of specific strain energy, focusing on the calculation of energy increments and the interpretation of strain energy in different material cases. It also discusses the homogeneity of specific energies, the relationship between hardness and elastic limit, and the measurement of toughness. The instructor explains the formulas for purely elastic works and provides examples of linear and exponential functions. Additionally, the lecture explores the tenacity as the specific strain energy until failure and the various methods for measuring hardness. Emphasis is placed on the importance of tough materials that require significant force and energy to deform.
