Hill Engineering is officially going global!
We are proud to announce we’ve been issued our first Japanese patent for the DART™, our Device for Automated Residual stress Testing.
Continue reading Hill Engineering issued first Japanese patent for the DART!TrueSlot® is an innovative technique for measuring near-surface residual stress that is more reliable than conventional techniques.
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.
Additionally, TrueSlot® is globally less invasive than slitting because the volume of removed material is localized to the surface and does not typically extend through most of the specimen thickness.
The physical application of TrueSlot® is like hole drilling, however instead of a shallow hole being milled into the body of a specimen containing residual stress, the material removed is a shallow slot. The strain released with each incremental slot depth is measured near the slot using a strain gage.
TrueSlot® is useful for
TrueSlot® was found to have better repeatability when compared with conventional x-ray diffraction.
