Material Properties: Stress-Strain Curve

This lecture covers the stress-strain curve, elastic limit stress, safety factor, material properties, and failure criteria. It explains the regions and important points of the stress-relative strain curve, fracture resistance, and different material behaviors. The instructor discusses the yield strength as a failure criterion, the factors influencing fracture resistance, and the importance of considering the plastic domain of ductile materials. Additionally, it explores the concepts of rigidity, malleability, ductility, brittleness, toughness, resilience, and impact resistance in materials.
