Shear Performance Mechanism Description Using Digital Image Correlation

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 Analyses Using Moving Least Squares Approximation

Introduction Moving least squares approximation is one kind of meshless methods in which the approximation is built from nodes only. Comparing to mesh-based methods, meshless methods have advantages on (1) refining is simpler to incorporate, (2) moving discontinuities can be treated easily, (3) large deformation can be handled robustly, (4) higher-order continuous shape functions, (5) non-local...

Pointwise Digital Image Correlation Using the Genetic Algorithm Optimization Method

In this paper, the use of the Genetic Algorithm (GA) optimization method for measuring displacement fields with the Digital Image Correlation (DIC) technique is investigated. The conventional kinematic description of deformations within a subset are restricted to constant displacements along with constant first or second order displacement gradients throughout the subset, which effectively acts...

Evaluation of Fiber Reinforced Cement Using Digital Image Correlation

The effect of short fiber reinforcements on the mechanical properties of cement has been examined using a splitting tensile - digital image correlation (DIC) measurement method. Three short fiber reinforcement materials have been used in this study: fiberglass, nylon, and polypropylene. The method outlined provides a simple experimental setup that can be used to evaluate the ultimate tensile st...
