SUMMARY
The discussion centers on the concept of Elastic Modulus, specifically Young's Modulus, and its behavior during tensile and bending tests. The formulas provided for calculating Elastic Modulus are E = L*F / A*ΔL for tensile tests and E = F*L^3 / 4*w*t^3*D for bending tests. It is established that Elastic Modulus is an inherent property of metals, remaining constant regardless of specimen size or applied force, due to the isotropic nature of metallic bonds. The discussion concludes that while Elastic Modulus is independent of geometry, properties beyond the elastic limit can vary based on factors like grain size and microstructure.
