Complex investigations of the development of micro- and macro-cracks in concrete members: experiments and discrete element method modelling
The scientific goal of the project is to explain the mechanism of propagation of elastic waves at the meso-level and their interaction with micro- and macro-cracking in concrete members subjected to monotonic quasi-static loading. This mechanism will be described by means of the advanced mathematical model based on the extended discrete element method (DEM). Because concrete has a particular structure that is discontinuous and heterogeneous, DEM is a suitable tool for investigating its mechanical behaviour at the aggregate level (meso-level). The DEM approach will allow for a precise reconstruction of the meso-structure of concrete and analyses of the evolution of micro- and macro-cracks and propagation of elastic waves at the level of aggregates during concrete deformation. The measurable effect of the project implementation will be papers published in journals indexed on the JCR list.

Characterization of fracture process in polyolefin fibre-reinforced concrete using ultrasonic waves and digital image correlation
PublicationThis study explores the monitoring of the fracture process in concrete beams and aims to characterize the evolution of damage in polyolefin fibre-reinforced concrete beams by utilizing the integrated application of two measurement techniques, digital image correlation and ultrasonic testing. The interpretation of registered wave time histories data was provided by the calculation of the magnitude-phase-composite metrics. An efficient...
