3D Full-Field Strain Measurement

MHDIC Three-dimensional Digital Image Correlation Full-Field Strain Measurement

Digital Image Correlation (DIC) is a 3D, full-field, non-contact optical technique to measure contour, deformation, vibration and strain on almost any material. The technique can be used for many tests including tensile, torsion, bending and combined loading for both static and dynamics applications. The method can be applied from very small (micro) to large testing areas – and the results are readily comparable with FEA results or strain gauges.

Fields of Application

1)Materials testing(Yang's modulus, Poisson's ratio, elastic-plastic performance parameters)

2)Components and parts testing(displacement measurement, strain measurement)

3)Biomechanics (bones, muscles, blood vessels, etc.)

4)Analysis of morphology and strain(micron-scale, nanometer-scale)

5)Fracture Mechanics

6)Verification of Finite Element Analysis (FEA)

7)High-speed deformation measurement(dynamic measurement, instantaneous measurement)

8)Dynamic strain measurement, such as fatigue test

9)Real-time measurement of the FLC-curve

Technical Features

1)Non-contact dynamic measurement. Obtaining the full-field three-dimensional coordinates, displacement, and strain data.

2)Multi-mode 3D display of the measurement results

3)Suitable for any material

4)Fast, simple and high-precision calibration

5)Measurement format: from 4mm to 4m

6)Range of strain measurement: from the minimum of 0.01% to the maximum greater than 1000%

7)Flexible and easy trigger function; free adjustment of acquisition frequency

8)Multithreaded computing; higher computing speed

9)32-bit or 64-bit operating system

Principles of Measurement

Based on Digital Image Correlation(DIC), binocular stereo vision technology and industrial close range photogrammetry, XTDIC offers a potable, high-speed, high-precision and simple operation solution for three dimensional coordinates, displacement and strain measurement during deformation by tracking the speckle patterns on the tested object surface.


Easy to Operate

Based on photogrammetric cameral calibration, XTDIC offers a fast, high-precision and easy calibration solution for different measurement ranges of the formats. Equipped with a crane, it is easy to operate. Various types of light sources provide good illumination conditions for different environment measurement. Multi-function control boxes provide a variety of A/D acquisition, D/A output and trigger function, meeting coordinated operation of peripherals and loading devices.

Software Functions

1)Support two or three dimensional deformation measurement simultaneously

2)Flexible camera calibration, supporting external image calibration

3)Providing flexible and convenient parameter-setting for image acquisition, satisfying the needs of image acquisition in different conditions

4)Flexibly select the object range of interest, improving processing efficiency

5)Flexibly set the size and step length of speckle to meet user requirements of different accuracy and resolution

6)High speed strain computing,providing eighteen different types of results of deformation and strain

7)3D display of calculating results, flexible 3D display

8)Multiple post-processing functionalities, including filling holes by interpolation, data smoothing, etc.

9)Coordinates conversion

10)Various analysis of section line, single point and point pair

11)Curve plotting

12)Report form of measuring and analysis results

13)Synthetic videos of measurement results, pictures and curves
