Mechanical Testing of Materials and Metals

Summary

The video traces the evolution of material strength testing, beginning with the earliest hardness tests from 1722. It covers the advent of the tensile test in the 1890s, which remains the gold standard, and introduces the Charpy impact test in 1901 for measuring fracture energy. The video concludes by highlighting the emergence of indentation plastometry, a modern, faster alternative to tensile testing that measures stress-strain curves and material strength in under three minutes. This new technique simplifies testing and provides more efficient results, marking a significant leap forward in material testing methods.
