New Case Study – TrueSlot®

Our latest case study is up and it’s all about TrueSlot®, our innovative technique for measuring near-surface residual stress!

TrueSlot® is a residual stress measurement technique for generating a profile of residual stress versus depth from the material surface. The stress computation is similar to slitting but offers more sensitivity near the surface due to the proximity of the strain gage.

TrueSlot® is one of the measurement types available through our DART™ system.
