Introduction

Understanding how materials respond to external forces is fundamental to safe and efficient engineering design. The study of material stress behavior provides engineers with essential tools to evaluate the strength, stability, and reliability of components and structures under real-world loading conditions.

This 5-day training program focuses on the core principles of stress in materials, including stress-strain relationships, axial and shear loads, torsion, bending, and combined stresses. Participants will gain both analytical skills and engineering intuition to evaluate material response, ensure safety, and support design optimization across structural and mechanical applications.
