MTS3000-Restan
Automatic system for measuring residual stresses
by the hole-drilling strain gage method
The EVAL 8 software, developed by SINT Technology, is a complete and customizable software for data analysing of the hole-drilling residual stress measurements.
The EVAL 7 software can be used with any previous version of the MTS3000-Restan system or in alternative by any operator that performs residual stress measurements by the hole-drilling.
Of course, the EVAL 8 software is fully compliant with the international ASTM E837-20 standard for residual stress measurements by the hole-drilling strain-gage method.
Moreover it offers several features for pre-processing the data, for the calculation of the residual stresses and finally for the post-processing and exporting of the results.
The EVAL software can be provided in 5 different versions (BASIC, PROFESSIONAL, PREMIUM, ENTERPRISE and ULTIMATE) depending on the features needed for specific applications.
The Main Features of the EVAL 8 software
The EVAL software offers a wide range of different calculation options as:
- ASTM E837 for uniform stress field;
- ASTM E837 for non-uniform stress field:
- Integral method;
- Differential method (Schwarz – Kockelmann method);
- HDM method (Influence function method).
It also allows the corrections of the most typical sources of measurement errors as:
- Eccentricity between the drilled hole and the centre of the strain gage rosette;
- Local Plasticity generated around the drilled hole (for uniform stress field calculation);
- Bottom-Hole Chamfer generated by the drilling process;
- Intermediate Thickness of the specimens under test.
- Surface detection error
New advanced features include also:
- A database with more than 4000 engineer materials;
- Advanced tools for the interpolation of the acquired strain using polynomial or spline alghoritms based on a single or a double interpolation curve;
- Extension of the calculation coefficents for any strain gage rosette for hole drilling measurement available on the market;
- Advanced version of the ASTM E837 calculation including all the corrections and the Tikhonov regularization;
- Evaluation of the measurement uncertainty for uniform and non-uniform stress field;
- Customizable PDF report including logo, references and details of your company;
