Abstract
Purpose: The aim of this work is computer simulation of the dynamic strength of masonry fragment under impact load of various intensity and contact angles. Design/methodology/ approach: Numerical calculations are performed on the RANET-3 software package allowing 3D simulation of impact, explosion and powerful radiation using the finite element analysis oriented towards the solution of dynamical problems. Stress states of masonry are studied in its interacting with the weight drop at different time points. Research findings: A mathematical model is proposed to simulate the impact interaction between the masonry fragment and a 1000 kg weight drop. The fracture of masonry is shown due to the impact load of various intensity and contact angles of 0, 30 and 45 degrees. Practical implications: The obtained results can be readily used in design and reconstruction of rooms in civil buildings into protective shelters and other civil defense buildings. Value: SNiP 88.13330.2014 ‗Civil defense buildings‘ is being currently revised, and the mathematical simulation of the dynamic fracture of masonry due to the impact load are therefore rather relevant.
