701. Precise strain analyses in the small deformation range using DIC measurement data and approximation-based smoothing

Thomas Lehmann

In the field of experimental mechanics, strain is a very frequently measured variable. Furthermore, the experimental determination of inhomogeneous strains is often necessary. This requires powerful field measurement methods which, due to their characteristic, have a high information density. One measurement method that is becoming increasingly important in this context is digital image...

702. Damage analysis of power engineering steels supported by DIC/ESPI techniques

Damage development in power engineering steel structures requires instant monitoring to maintain their properties, ensure the safety of working components, and estimate their service life. One should highlight, that the operational loads and simultaneous microstructural changes occurring due to high-temperature exposure accelerate the development of damage dynamics significantly. Thus, it is...

703. Determination of fatigue characteristics in the normal stress-fatigue life system

The paper presents experimental methods for determining the fatigue characteristics of various materials. Basic fatigue characteristics are obtained under tension-compression loads. However, few structures work in this system. More often we are dealing with some form of bending. In this case, we are also dealing with variable normal stresses. However, these characteristics are not the same....

704. Challenges and solutions in optical measurement methods for experimental mechanics applications

In this research talk, we delve into the intricacies of selected optical measurement techniques applied to experimental mechanics of complex and big (in relation to the actual field-of-view) objects. The focus is on two major approaches: multimodal measurements and synthetic aperture. We explore the challenges faced by two groups of experimental methods: (i) digital image correlation (or...

705. Deformation and temperature determination using DIC/TG measurement

Stefan Hartmann

08/04/2025, 15:20

In digital image correlation (DIC) different methods to determine the displacements fields on the surface of a specimen are proposed in the literature. Here, we assume that a commercial DIC system provides the three-dimensional coordinates of material points on the curved surface of a specimen, and one does not have any access to the pixel data. Based on this point cloud data, a point on the...
