Explore the fundamentals of structural integrity through stress, shear, and failure analysis. This video breaks down how materials and components respond to applied loads, including tensile, compressive, bending, and shear stresses. Learn how stress concentrations, improper load paths, and material defects lead to yielding, fatigue, and catastrophic failure. Designed for mechanical and structural engineers, this episode provides practical insight into failure modes, safety factors, and design principles required to ensure reliable, code-compliant structures in real-world applications.
