High-speed three-dimensional digital image correlation (3D-DIC) techniques can acquire
full-field vibration responses under a single excitation, which is not restricted by the number …

The theoretical part of the paper presents the framework of the digital image correlation
(DIC) method as well as its advantages and limitations. The DIC technique that can be used …

Rotating structures are of interest in many engineering fields, where knowing their dynamic
behaviour is important to prevent undesired operating states. However, the experimental …

The paper deals with the use of 3D digital image correlation in determining modal
parameters of mechanical systems. It is a non-contact optical method, which for the …

This study aims to develop an effective method to identifying modal parameters of vibrating
structures using digital image correlation (DIC) technique, in which singular value …

The present paper discusses a new approach for the experimental determination of modal
parameters (resonant frequencies, modal shapes and dam** coefficients) based on …

Traditional modal testing has difficulty accurately identifying the ultralow-frequency modes of
flexible structures. Ultralow-frequency excitation and vibration signal acquisition are two …

The paper presents a numerical model based on the finite element method (FEM) to predict
deformations and residual stresses in socket welding of different diameter stainless steel …

A low-cost method is presented which enables digital image correlation (DIC) with
conventional cameras (ie not high-speed) to be used for determination of vibration deflected …

Sound visualization tools are now widely used in industry. As a tool, acoustic cameras are
also well-suited for faster identification of errors as well as individual states while operating …
