Macroscopic Stress Peak

A macroscopic stress raiser is a visible, strong concentration of stress in a part. It can cause cracks and ruin the material.

Physical-Chemical Mechanism of Action

A macroscopic stress peak is a visible, strong concentration of mechanical loads on a component. These stresses can concentrate at cross-section transitions or notches.

Metallurgical Relevance & Welding Risks

A macroscopic stress peak can lead to crack growth and plastic flow. This increases the risk of hot cracks and material failure. In the worst case, it can cause component failure.

Workshop Practice & Action Instructions

Avoid macroscopic stress peaks by careful component design and correct welding techniques. Keep stresses under control by smoothing notches and loading the material evenly.
