“…For a better understanding of the deformation process, an investigation with digital image correlation (DIC) is often beneficial. Therefore, Adorna et al [1] compared different DIC tools. DIC in general visualizes local strain fields and thereby helps to understand the mesomechanical deformation with a sub-pixel accuracy for example, in a failure investigation on the surface of a specimen [61].…”

Cellular materials such as metal foams or auxetic metamaterials are interesting microheterogeneous materials used for lightweight construction and as energy absorbers. Their macroscopic behavior is related to their specific mesoscopic deformation by a strong structure‐property‐relationship. Digital image correlation and infrared thermography are two methods to visualize and study the local deformation behavior in materials. The present study deals with the full‐field thermomechanical analysis of the mesomechanical deformation in Ni/PU hybrid foams and Ni/polymer hybrid auxetic structures performing a correlative digital image correlation and infrared thermography. Instead of comparing and correlating only the primary output variables of both methods, strain and temperature, also strain rates and temperature rates occurring during deformation were compared. These allow for a better correlation and more conclusive results than obtained using only the primary output variables.
