A Digital Image Correlation Algorithm with Light Reflection Compensation

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...

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 ...

Stress Field Analysis of V-Notches with Tip Cracks in a Polymer Material Using Digital Image Correlation

In this study, displacement field around v-notches of a poly methyl metha crylate (PMMA) specimen with tip cracks will be analyzed using digital image correlation technique. First intensity factor in combination with in-plane rigid body translations and rotation components will be determined by linear least squares fitting of the displacement field data to the corresponding relations among stre...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
