Measurement and simulation of strain fields around crack tips under mixed-mode fatigue loading [PDF]
Fracture and Structural Integrity, 2015 For various configurations examined in a series of fatigue experiments on thin-walled tubes under tension and torsion, the experimental results – crack path, crack growth life, near crack tip deformations, and crack closure – are measured and compared to

Digital Image Correlation Employing Thermal Marking
Physical Sciences Forum, 2022 Digital image correlation (DIC) is a widely used technique that makes it possible to obtain full field displacements, as well as 3D shapes, even at high speeds. However, it requires a pattern of random spots to be sprayed onto the surface, which would be

Fatigue & Fracture of Engineering Materials & Structures, 2021 The occurrence of fatigue cracks is an inherent part of the design of engineering structures subjected to nonconstant loads. Thus, the accurate description of cracks in terms of location and evolution during service conditions is man-datory to fulfill ...

Mechanics-aided digital image correlation [PDF]
The Journal of Strain Analysis for Engineering Design, 2013 By construction, digital image correlation is an ill-posed problem. To circumvent this difficulty, regularization is often performed implicitly through the kinematic basis chosen to express the sought displacement fields. Conversely, a priori information on the mechanical behavior of the studied material is often available.

Materials Today, 2010 Strain and displacement are critical parameters within engineering and construction projects. However, measuring these parameters outside of the lab requires a difficult choice between conventional techniques, as accuracy, simplicity and cost must all be balanced. Digital Imaging Correlation (DIC) is a technique which may prove to be ideally suited for
