Abstract T he behavior of porous, segmented, 50% porosity aluminа under uniaxial compression loading has been studied using digital image correlation (DIC) method. The main stages of fracture were high-lighted as well as qualitative and quantitative characteristics given. In the process of compressing the sample, a series of images of the material surface was obtained. The use of the DIC technique made it possible to obtain a series of displacement vector fields, and the corresponding spatial distributions of deformation were transformed into pseudo-images. The use of the DIC algorithm made it possible to obtain the fields of deformation vectors on their basis. © 2022 The Authors. Published by ELSEVIER B.V.

Keywords: segmented ceramics; digital image correlation; deformation; tensor components; deformation vector fields; fracture 1. Introduction When developing new structural materials, it is necessary to study in detail their physical and mechanical properties in order to find an optimal production regime as well reduce the costs for assessing the current mechanical state of the structure and increase its reliability in service. A large amount of information could be obtained from studying evolution of the material deformation under mechanical loading.
