Digital fringe projection (DFP) profilometry has been widely used to generate threedimensional (3D) surface information. In this work, a novel 3D shape measurement system based on DFP technique is proposed for accurate and quick thin film/rivulet flow measurement. The key concept of the technique is making use of digital image correlation (DIC) algorithm to direct calculate the projected grid p...

Abstract In this paper, fatigue damage development of 14MoV6-3 (13HMF) power engineering steel was studied through different experimental and analytical approaches. The specimens machined from the as-received pipe were subjected to loading simultaneously monitored using digital image correlation (DIC) technique. analysed microstructural observations fracture surfaces further described as a func...

Abstract The aim of this research was to compare the effectiveness two different optical measurement techniques (digital image correlation—DIC and electronic speckle pattern interferometry—ESPI) during fatigue damage development monitoring in X10CrMoVNb9-1 (P91) power engineering steel for pipes. specimens machined from as-received pipe were subjected loadings monitored simultaneously using DIC...

The digital image correlation (DIC) method is widely used in deformation measurement due to the advantages of being non-contact, high precision, full field measurement, and requiring simple experimental equipment. Traditionally, grayscale speckle patterns captured by a monochromatic camera are DIC method. With growing development consumer color cameras, there great potential for developing info...

This paper presents the design and implementation of a novel method for real time material and structure parameters estimation. Digital image correlation (DIC) and particle filtering (PF) are used for obtaining the full-field deformations of a structure or model. In order to take into account all advantages of both methods, new marker design is proposed. Particle filtering method is also used i...

A progressive FEA mechanical fatigue degradation model for composites was developed and implemented using a UMAT user material subroutine in Abaqus. Numerical results were compared to experimental strain field data from high frequency digital image correlation (DIC) of split disk testing pressure vessel cut outs with holes. The correctly predicted the onset evolution damage matrix as well fiber...

This work developed a method that uses single monochrome high-speed camera without sacrificing the spatial resolution to measure both in-plane and out-of-plane full-field vibrations. By using two-dimensional digital image correlation (2D-DIC) algorithm, first extracts displacement field from measured virtual strains. Then it retrieves after eliminating motion-induced component. For validation, ...

<p>As reinforced concrete structures reach the end of their design lives, technology for improving accuracy and efficiency inspections structural health monitoring rapidly progresses. Concrete cracking reinforcement strains are two relevant parameters in assessing damage safety these structures. The use Digital Image Correlation (DIC) systems distributed Fibre Optic Sensors (FOS) to evalu...

The recent development of efficient 3D imaging tools such as X-Rays computed microtomography combined with the extension to volumetric images of Digital Image Correlation (DIC) techniques provide new insights on the analysis of materials and structures. Among many other possible fields of application, geomaterials are good candidates for such investigations, owing to their relative transparency...

Abstract To investigate the influence of global plastic deformations on girth weld defect tolerance in pipelines, a parametric finite element model has been developed. This paper provides an experimental validation of the model. It describes the test setup and instrumentation used for the evaluation of plastic strain fields around a notch in a tension loaded non-welded X65 mini wide plate. LVDT...
