Introduction
Product Introduction & Applications
The Anti-Crack Fatigue Tester is designed to evaluate the fatigue resistance and crack propagation characteristics of materials under cyclic loading conditions. By simulating repeated stress and strain, it measures how materials behave under long-term fatigue and helps identify potential failure points.
This tester is widely used in:
Material Research & Development: Assessing durability and fatigue properties of metals, plastics, composites, and coatings.
Quality Control: Ensuring product consistency and performance under cyclic stress.
Industrial Testing: Supporting aerospace, automotive, and construction industries with fatigue evaluation data.
