Study Notes
Compression Testing
- Three types of stresses are created in an object during compression testing: compressive stress, shear stress, and tensile stress.
Test Specimens
- Standard sizes and dimensions are used for test specimens in compression testing to ensure accurate and comparable results.
Specimen Dimensions
- If a compression test specimen is too short, it may bulge or deform excessively, leading to inaccurate results.
- The length of the cylinder should be at least twice the diameter for satisfactory results in compression testing to prevent bulging and ensure uniform stress distribution.
Compressive Strength
- Compressive strength is most useful for comparing the resistance of different materials to crushing or deformation under compressive loads.
