Universal Testing Machines (UTMs) handle several key tests to measure material mechanical properties. Here’s a quick look at the main ones:
Tensile Testing
- Pulls a sample until it breaks
- Measures tensile strength, elongation, and elasticity
- Shows how much a material can stretch before failing
Compression Testing
- Pushes a sample to check how much load it can bear
- Measures compressive strength and deformation
- Useful for materials in load-bearing applications like concrete and metals
Flexural (Bend) Testing
- Bends a material sample to assess resistance
- Measures flexural strength and modulus
- Important for plastics, composites, and construction materials
Shear Testing
- Applies force parallel to the surface
- Measures shear strength of adhesives, welds, and joints
- Checks how well materials hold together under sliding forces
