Dantec Dynamics Presents Shearography NDT Products

26 September 2010

Dantec Dynamics will launch its latest Shearography and Digital Image Correlation systems during The Composites Engineering Show at the NEC in Birmingham.

Dantec’s Q-800 Shearography system, for NDT of composites, has new rugged electronics for in-service use to complement the existing rugged electronics for the Q-810, vacuum hood inspection system. The new Q-800 electronics are water and dust proof to IP65 with the laptop and connectors also conforming to MIL-STD 810G, which includes an outdoor readable screen. Meanwhile the Q-810 system now has a new heat loading frame to add to its vacuum loading capabilities.

Dantec’s ISTRA4D software for full field strain and deformation measurement now includes Real Time correlation with voltage output, 2D results overlay presentation and updates to allow analysis under Windows 7 and multi core systems. While for the hardware new cameras up to 16MP are fully integrated within the ISTRA4D platform.

Shearography is an optical non destructive testing technique used for inspecting composite materials. Benefiting from being an optical technique, Shearography can cover large areas quickly providing the user live results on the detection on delaminations, disbonds, wrinkles, impact damage and much more beyond. Systems can be used as an R&D tool, for in-service inspection or as a fully automated production system. The RAF is the UK’s largest user, using the Q-810 vacuum hood system for in-service inspection of the Sentry aircraft.

Digital Image Correlation (DIC) is also an optical technique, measuring strain and deformation. DIC provides full field, 3D, non contact results over a flexible measuring range of mm to m on any material. It is ideal for material testing, component testing, FEA validation, high speed impacts and vibration analysis.
