Abstract
The study represents the mathematical model of distorting and destruction of ordinary brick and masonry when subjected to shock-wave loadings. The research of the impact dynamic strength of the masonry's two fragments to the steel drop-weight of 1-2 m, weighing 197-1000 kg, was conducted by using the method of the computer modelling.
Highlights
For the civil structures, it tends to increase the origination and the short-time load action of shock and bursting conditions.In Tomsk State University of Architecture and Building, the symbolic behavioural model was generated, taking into consideration the shock-wave loading of one-piece structure environments, including concrete, reinforced concrete, and fiber reinforced concrete, to make the strength design of the structural engineering elements to the explosion and to the impact loading.The studies of the structural behaviour, containing the masonry when subjected to shock-wave loading, are egregiously insufficient
The mathematical modelling and the calculations of brick structures when subjected to the dynamic loadings are meant to be an essentially relevant objective
During the mathematical model development of the distortion and the destruction of ordinary brick it is necessary to take in account its original porosity, which can amount to 13%
Summary
It tends to increase the origination and the short-time load action of shock and bursting conditions. In Tomsk State University of Architecture and Building, the symbolic behavioural model was generated, taking into consideration the shock-wave loading of one-piece structure environments, including concrete, reinforced concrete, and fiber reinforced concrete, to make the strength design of the structural engineering elements to the explosion and to the impact loading. The studies of the structural behaviour, containing the masonry when subjected to shock-wave loading, are egregiously insufficient. The mathematical modelling and the calculations of brick structures when subjected to the dynamic loadings are meant to be an essentially relevant objective. The mathematical model of porous elasto-plastic environment is described by the mass impulse, the energy conservation equations, the equation of state, the PrandtlReuss equation, the Mises yield criterion and the equation of the porous substance. Two fracture processes are dealt with stretching and pressure for the elastic-plastic porous substance
