Material Testing
A systematic process of evaluating the physical, chemical, and mechanical properties of materials to determine their behavior and suitability for specific applications.
Material testing represents a crucial intersection of experimental design and systems analysis, where materials are systematically evaluated through standardized procedures to understand their properties and behaviors under various conditions.
The practice emerged from the need to ensure system reliability and operates as a form of feedback control in manufacturing and engineering processes. Through material testing, engineers and scientists can establish predictive models of material behavior and validate theoretical assumptions.
Key aspects of material testing include:
- Mechanical Properties
- Stress-strain relationships
- Fatigue resistance
- Hardness testing
- Impact resistance
