Investigation of influence of defectiveness in aluminous porcelain structure on fracture process under compressive loading using acoustic emission method
This work presents acoustic emission (AE) and microscopic study of ceramic samples
subjected to compressive stress. The object of research were specimens made of insulator aluminous
porcelain 130 type. Purpose of this work was registration the stages of the process
of degradation in ceramic material structure. Microscopic study allowed observing structural
parameters of material before loading and on particular stages of the process of defects development.
Influence of technological faults existing in material structure on mechanical-acoustic
characteristics and mechanical strength of the samples was recognized.
