Automated residual stress measurements
Near-surface residual stress data is critical when assessing material performance, optimizing design, validating models, evaluating field failures, and executing quality assurance programs. Hill Engineering’s DARTTM is an industry-leading tool for efficient, precise, and reliable near-surface residual stress measurements. The DARTTM overcomes limitations of existing residual stress measurement equipment and includes everything required to perform state-of-the-art measurements in accordance with industry specifications.
Intuitive
Residual stress measurements with the DARTTM are easy to complete. A user interface guides you through set-up, then takes over for automated measurement execution and residual stress calculation.
Efficient
With measurements completing in less than 60 minutes, the DARTTM excels in the production quality management environment. Automated data capture, processing, and archiving provide you with residual stress results instantly.
Reliable
Featuring advanced cutting strategies and real-time quality checks, the DARTTM gives you confidence in your residual stress data.
