SOFTWARE MEASURING TOOLS

A – AXIAL STRAIN

point probe line horizontal

Allows for measurement of axial strain in real-time. In addition to the elementary measuring probes such as Point probe and Line probe, the Alpha Axial Strain measurement module includes the Extreme Line probe that divides the length of the specimen into multiple precisely defined gauge segments and detects the necking area. This function provides an advantage over conventional single-position measurement, wherein a rupture outside the gauge length area causes test invalidity.

T – TRANSVERSAL STRAIN

point probe bend line trans line horizontal

Allows for measuring of transversal strain in real-time. In addition to the elementary measurement probes such as Point probe and Line probe, the Alpha Transversal Strain measurement module includes the Trans Line probe with the edge detection feature. The Trans Line offers single or multiple line width measurement. This is an advantage over the conventional single-position measurement. All lines can be averaged for a precise Poisson’s ratio reading. The transversal module does not support axial strain measurement.

TR – TORSIONAL

torsion line horizontal

Allows for measurement of angular twist on cylindrical specimens in two positions. Usable in static and dynamic applications. This module is an extension and works only with the A or T modules.

TORSION LINE PROBE

PP – POST PROCESS

This module unlocks a remarkably efficient tool for processing of previously recorded tests with sub-sequent playback and data export. Each real-time measurement method can have multiple offline records with a custom probe layout. Post-Process is an optimal solution for measurement of unique or expensive specimens and components.

POST PROCESSING

DIC AREA

DIC area

This module provides a strain or displacement distribution map, thereby enabling to obtain maximum available data from each experiment. This feature surpasses other technologies on the market. It helps users all over the world not just to improve the understanding of their experiments, but thanks to an easily interpretable output, also to sell their results effortlessly.

2D DIC AREA

3D

The 3D module combines Digital Image Correlation (DIC) with stereo vision, unlocking complex functionality for measuring displacement and surface strain fields of 3D objects. It is the most universal measurement method within DIC systems, offering unparalleled versatility and precision. This module stands out as the most comprehensive solution for analyzing the mechanical behavior of materials and structures in three dimensions, making it an indispensable tool for a wide range of applications in research and industry.

3D DIC AREA

3D VE FULL

The 3D VE FULL module is a video extensometer functionality, eliminating the need for the test sample’s movement to be confined to a single plane during experimentation. It incorporates line-based probes for precise measurement and requires the marking of the sample for accurate tracking and analysis.

3D VE PLANAR

The 3D VE PLANAR module is designed for video extensometry applications on samples that are initially flat and may possess reflective surfaces. This module allows for the analysis of such materials without the necessity of marking the samples. At the start of the test, it is crucial that the sample be positioned in a plane to ensure accurate measurements.

DIN – DEVICE INPUT

Enables real-time import of external values concerning force, motion, or temperature as an analog or digital signal into Alpha. Useful mainly for post-processing or measurements taking place outdoors.

CL – CRACK LENGTH

Crack Probe

This module is designed for crack length measurement of compact tension (CT) or double cantilever beam (DCB) specimens. Line probe function is included in the CL module. Line probe enables crack opening measurement providing results comparable to conventional devices.

CRACK LENGHT PROBE

LVD – LINE VALUE DISTRIBUTION

LVD probe

While a full-field strain distribution via DIC Area analysis usually requires post-processing due to a high number of computational points, the Line Value Distribution module provides a colourful value visualization feature that is more feasible during real-time measurements. It is supported by most types of probes that are divided to line segments, specifically strain distribution for Extreme, ROD and Bend Lines, including an additional choice of Deflection or Curvature for Bend Lines.
