Investigation of acoustic emissions and pressure stimulated currents detected during bending of restored marble epistyles within the frame of log-periodic power-law models

Abstract

The deformation of solid materials is a procedure which is accompanied by numerous effects like the emission of acoustic and electromagnetic signals or the generation of pressure stimulated currents. In the present work, we focus on the study of acoustic emissions and pressure stimulated currents detected during a recent bending experiment on an accurate copy of an authentic marble epistyle of the Parthenon Temple. The aim is to investigate the emitted acoustic signals and pressure stimulated currents within the frame of log-periodic power-law models. While acoustic and electromagnetic emissions detected during deformation experiments of well-defined and specially crafted specimens have already been successfully described by such models, it is interesting to investigate whether these models could also describe pressure stimulated currents as well as acoustic emission signals originating from complex structural setups.
