NUMERICAL SIMULATIONS OF MECHANICAL PROPERTIES OF ALUMINA FOAMS BASED ON COMPUTED TOMOGRAPHY

摘要

The aim of this paper is to apply the results of microtomography of alumina foam to create a numerical model and perform numerical simulations of compression tests. The geometric characteristics of real foam samples are estimated from tomographic and scanning electron microscopy images. The performance of the reconstructed models is compared to experimental values of elastic moduli. A preliminary analysis of failure strength simulations under compression of alumina foam is also provided.
