Understanding Bending Stress: Elastic vs. Plastic Deformation in Profile Forming

This article explains how bending stress shapes aluminum and steel profiles, contrasting elastic deformation (reversible) with plastic deformation (permanent). It discusses springback, stress-strain curves, and how engineers use this knowledge to predict behavior and avoid cracks or distortion. Practical considerations include material choice, proper bend radius, tooling selection, and simulation for complex bends, ensuring accuracy and durability in production.
