Digital image correlation (DIC) for measuring strain in brick masonry specimen using Ncorr open source 2D MATLAB program

Ncorr: Open-Source 2D Digital Image Correlation Matlab Software

Digital Image Correlation (DIC) is an important and widely used non-contact technique for measuring material deformation. Considerable progress has been made in recent decades in both developing new experimental DIC techniques and in enhancing the performance of the relevant computational algorithms. Despite this progress, there is a distinct lack of a freely available, high-quality, flexible D...

STRAIN MEASUREMENT IN A SPECIMEN SUBJECTED TO OUT-OF-PLANE MOVEMENT: Using an Open-Source Digital Image Correlation-Based Tool

Niranjan Desai did his PhD from the University of Louisville and is an Assistant Professor in the department of Civil and Mechanical Engineering at Purdue University Northwest. His areas of interest include structural health monitoring and nonlinear dynamic analysis. Thomas Pfauth earned a BS degree in mechanical engineering with a minor in electrical engineering in May 2017. Areas of interest ...

Displacement monitoring of a Long-Span Arch Railway Bridge using Digital Image Correlation (DIC)

There is an escalating demand for condition monitoring enhancement of transport infrastructures worldwide. Bridges are of vital importance in transportation infrastructure and need such monitoring. In this research, a non-contact vision-based technique called Digital Image Correlation (DIC) was used to calculate the bridge displacements. A high frame rate camera with 4K capability was used for ...

Digital Image Correlation of 2D X-ray Powder Diffraction Data for Lattice Strain Evaluation

High energy 2D X-ray powder diffraction experiments are widely used for lattice strain measurement. The 2D to 1D conversion of diffraction patterns is a necessary step used to prepare the data for full pattern refinement, but is inefficient when only peak centre position information is required for lattice strain evaluation. The multi-step conversion process is likely to lead to increased error...
