SOFTWARE MEASURING TOOLS

POINT     Point Probe

A basic measuring probe for displacement determination.

LINE     Line Probe

An elementary measuring probe for strain and length determination.

TRANS LINE     Trans Line Probe

Offers a multi-positional transversal measurement with averaged and max/min width functions.

EXTREME LINE     Extreme Line Probe

Probe for axial neck detection. Provides improved E-modulus reading and eliminates invalid tests caused by failure outside the gauge length area.

BEND LINE     Bend Line Probe

A probe designed for bending tests. Measures strain over a curved shape and enables to visualize the real-time strain distribution.

TORSION LINE     Torsion Line Probe

Enables dual position angular twist and strain measurement.

LINE STRAIN DISTRIBUTION     Line Strain Distribution

Provides a colorful strain visualization feature during real-time measurement.

CRACK PROBE     Crack Probe

Measures crack length during static or dynamic tests.

DIC AREA     DIC Area

A full-field probe for strain and displacement distribution mapping.

ROD LINE     ROD Line Probe

Designed for rebar measurement, it compensates for the detachment of the oxide layer during testing. Includes the axial neck detection feature.

A – AXIAL STRAIN

Point Probe    Line Probe    Extreme Line Probe

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.

 

POINT PROBE

 

LINE PROBE

 

EXTREME LINE PROBE

T – TRANSVERSAL STRAIN

Point Probe    Bend Line Probe    Trans Line Probe

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.


POINT PROBES

 

BEND PROBE

 

TRANS LINE PROBE

AT – AXIAL & TRANSVERSAL STRAIN

Point Probe    Line Probe    Extreme Line Probe    Bend Line Probe    Trans Line Probe

A bundle of Axial and Transversal modules.

TR – TORSIONAL

Torsion Line Probe

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.

 

DIC AREA

 

 

3D – Stereoscopic DIC

Alpha 3D DIC combining DIC with stereo vision, can measure the 3D displacement field and surface strain field of 3D objects.

 

3D DIC AREA

 

 

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.

 

DEVICE INPUT

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 LENGTH PROBE

 

 

LSD – LINE STRAIN DISTRIBUTION

Line Strain Distribution

While a full-field strain distribution via DIC Area analysis needs post-processing due to a high number of computational points, the Line Strain Distribution provides a colorful strain visualization feature during real-time measurement.

As seen below, this functionality applies to various measurement probes included in other modules.
