The aim of this work was to monitor the mechanical behavior of 316L stainless steel produced by 3D printing in the vertical direction. The material was tested in the "as printed" state. Digital Image Correlation measurements were used for 4 types of notched specimens. The behavior of these specimens under monotonic loading was investigated in two l...

AbstractThe deformation behavior of 3D 03X17H14M2 steel samples with various lattice structures created by selective laser melting has been studied under compression conditions using the digital image correlation method. Spatially temporal patterns of localization of transverse (εxx) and longitudinal (εyy) deformations of topological structure actu...

The objective of this study was to evaluate rebound characteristics for running-specific prostheses by quantifying their dynamic behavior by an impact experiment. The impact experiment was conducted to produce a typical ground foot strike contact, and to obtain the dynamic behavior of blades during and after impact. The motion of the impactor and d...

AbstractWe present results of applying a combined approach to studying fatigue fracture processes in VT23 titanium alloy with a laser-welded joint. The approach involves fractographic examination using scanning electron microscopy and analysis of strain fields at the sample surface (using digital image correlation technique). Samples with permanent...

A problem for determining the center, size, and spatial distribution of displacements of a vortex on the basis of a plane vector field is under consideration. A seed algorithm is proposed instead of typical contour scanning, and specific circulation is used as a criterion for determining the center of a vortex flow. In order to increase the stabili...

The review of progress in numerical synthesis and study of strain sensors patterns, which can be used for realization of digital image correlation (DIC) and its applications in engineering practice, is presented. Problems related to monitoring a large area of an objects surface while subsequently increasing the image scale and concentrating observa...

Field and experimental observations showed that preslip undergoes a transition from multiple to single preslip zones, which implies the existence of linkage of preslip zones before the fault instability. However, the observations of the linkage process, which is significant for understanding the mechanism of earthquake preparation, remains to be im...

The paper deals with experimental studies of inhomogeneous strain fields in the “neck” region in extension of plane and cylindrical specimens at the postcritical stage, which directly precedes the fracture, by using a video system and a digital image correlation method. We consider the problems of interpretation of extension diagrams obtained for s...

A problem of identification of a shear-type solid flow is considered. Characteristics of the shear flow are determined on the basis of the initial displacement vector field. An algorithm of formation of a finite-size model displacement field of the shear type is given. A functional is proposed to search for the amplitude and direction of the shear ...

Plastic brackets, as well as ceramic brackets, are used in various cases since they have excellent esthetics. However, their mechanical properties remain uncertain. The purpose of this study was to determine how deformation and stress distribution in esthetic brackets differ among materials under the same wire load. Using the digital image correlat...
