(#102)Yield Strength Stress and Eccentric Joint Failure

Mechanical Engineering Made Simple · Feb 20, 2026 · 17m · transcript

This episode breaks down yield strength, stress behavior, and eccentric joint failure from a real engineering perspective. Learn how materials transition from elastic to plastic deformation, how normal and shear stresses interact, and why yield strength, not ultimate strength, often governs safe design. We examine what happens when loads are applied off-center, creating combined bending and direct stress that amplify peak fiber stress beyond what simple axial calculations predict.

You’ll see how eccentric loading shifts the neutral axis, increases stress concentration, and accelerates fatigue…
