Granular micromechanics approach (GMA) provides a predictive theory for granular material behavior by connecting the grain-scale interactions to continuum models. Here, we have used GMA to predict the closed-form expressions for elastic constants of

International audience; Mechanical tests designed to measure classical behavior do not provide information underlying the macroscale response. Multiscalar digital image correlation (DIC) can be employed in these experiments to expose the micro-mechan

Publikováno v: Advanced Structured Materials ISBN: 9783030504632

In this work we present the results of an experimental parametric investigation of the mechanical behavior of the pantographic unit cells. The main goal is to determine extreme configurations of the geometric parameters of the microstructure. This wo

International audience; Recently the exotic properties of pantographic metamaterials have been investigated, and various mathematical models (both discrete and continuous) have been introduced. However, the experimental evidence available up to now c
