Testing Materials – Civil Engineering

Engineering Studies – H1 Civil Engineering – Materials and Manufacturing

This topic investigates methods of investigating material for cracks and defects, both destructive and non-destructive methods. Procedures for analysis and interpreting test data are key concepts for this topic.

Key Concepts

• Material testing categories such as:
  • Destructive
  • Non-destructive
• Interpreting test data
• Describing testing apparatus and procedures
• Explaining testing apparatus applications
• Measuring units

Discussion Questions

Testing

1. Why is testing of materials important?
