We're an MIT spinoff providing portable,

non-destructive metal strength testing

and seam identification services.

  • An NDE test that actually generates tension in the material to form a microcracking process similar to what occurs at the tip of a crack in service.
  • Faster and more accurate than any other alternative.
  • Just like the HSD Tester, it can characterize gradients across the material such as across welded seams and butt joints.
  • Supported by a team of experts in mechanics and materials.
    ​

All existing techniques are only in the lab.

They require destructive samples and extensive preparation time.

Instrument launch expected in 2018.

​​​Our portable Non-Destructive Toughness Tester (NDTT) generates a stress state nearly identical to the tip of an existing flaw. This unique characteristic will allow us to determine plane strain fracture toughness and ductile to brittle transition characteristics.



Leading academic faculty see this as a major breakthrough in material quality testing.

Proof of concept: Microscope image showing superficial  tension-induced fracture surface generated by NDTT prototype.

Charpy V-Notch Impact Test:

Provides ductile-to-brittle transition temperature.

Traditional Fracture Toughness Testing:

Requires large specimens.

The first and only surface test for index of toughness.
