Automatic system for measuring residual stresses
by the hole-drilling strain gage method
The RSM 7 software, developed by SINT Technology is a complete and customizable software for test setup and strain acquisition for the hole-drilling residual stress measurements.
The RSM 7 software can be used with the recent versions of the MTS3000-Restan system while another software option called hRSM can be provided for the manual version of the MTS3000-Restan.
Of course, the RSM 7 software allows to perform measurements fully compliant with the international ASTM E837-13a standard for residual stresses by the hole-drilling strain-gage method.
The RSM 7 software offers several different features depending on the measurement chain or the material under test: it allows to configure the depth increments, the strain gage acquisition and the preparation of the test (centering by optical or digital microscope), to determine the zero-depth surface and finally to measure the drilled hole.
The RSM 7 software can be provided in 2 different versions (BASIC and PROFESSIONAL) and in the manual version hRSM, depending on the features needed for typical applications.
The Main Features of the RSM 7 software
The main features of the RSM software are:
Automatic control of the whole process;
Full support for any testing configuration available with the MTS3000 – Restan device;
New Graphical layout with user-friendly wizards;
Bigger database regarding the material properties;
New continuous acquisition strategy of the strain signals;
Optional zero-setting sequence by strain reading;
Implementation of digital microscope control, hole measurement by image analysis & automatic determination of the eccentricity components;
Dummy gage configuration for measurements on polymeric & composites materials;
Possibility to connect an LVDT sensor for fine hole-drilling measurements;
Possibility to connect a thermocouple for thermal strain correction (mainly for field measurements).
