Universal Testing Machine (UTM)

The Universal Testing Machine (UTM) applies a load to a sample in either tensile, compression or shear to measure the mechanical properties of the material or component. This test is ‘destructive’, in many cases all the way to fracture.
- Measures the fundamental mechanical properties of metals, plastics, ceramics and composites destructively
- Mechanical response: stress vs. strain
- Tensile testing
- Load / Compression testing
- Shear testing
- Flexural, 3-point bend testing
- Simulate failure modes
- Determination of maximum load capacity of material or product to specification

Hardness Testing

Hardness is the resistance to localized plastic deformation. When an indenter of a given size and dimension is applied with a known force to the surface of a material, the size of the indentation left behind can be used as a measure of the material’s strength.

Vickers Hardness

  •     Diamond indenter
  •     Normally for mounted staples
  •     Measures width of indent 

Micro Vickers Hardness

  • Diamond indenter
  • Hardness traverse across weld, surface treatment
  • Measures width of indent

Rockwell B, C Hardness

  • Steel ball and diamond indent
  • Less sample preparation
  • Measures depth of indent 

Brinell Hardness

  • Large ball indenter: high loads
  • Castings, brittle materials
  • Measures width of indent
