The dynamic behavior of structures has always received considerable attention. The dynamic behavior of structures requires a suitable numerical modeling method for the behavior of structures under dynamic loads to be illustrated. In this study, the response of two identical unreinforced masonry walls to the underground blast was examined. The experimental variables were the horizontal distance from the explosion point and the depth in which the explosives were located. After examining the behavior of the masonry walls under high-frequency dynamic loads, different numerical models were applied to simulate the dynamic behavior of these two walls against the underground blast experiments. Thus, several different factors, including yield criterion, types of Meso and macro modeling for the masonry wall, and topography of the site were investigated. Finally, due to the degree of accuracy required, it was concluded that each of the methods can be used; however, the most appropriate and accurate modeling method for the unreinforced masonry wall is the frictional-cohesive zone material and modified Mohr-Coulomb model, which provided accurate and precise responses.

In this paper, a mathematical model for projectiles shooting in any direction based on sensors distributed stereoscopically is put forward. It is based on the characteristics of a shock wave around a supersonic projectile and acoustical localization. Wave equations for an acoustic monopole point source of a directed effect used for physical interpretation of pressure as an acoustic phenomenon. Simulation and measurements of novel versatile mechanical and acoustical damping system (silencer), which has both a muzzle break and silencer properties studied in this paper. The use of the proposed damping system can have great influence on the acoustic pressure field intensity from the shooter. A silencer regarded as an acoustic transducer and multi-holes waveguide with a chamber. Wave equations for an acoustic monopole point source of a directed effect used for the physical interpretation of pressure as an acoustic phenomenon. The numerical simulation results of the silencer with different configurations presented allow trends to be established. A measurement chain was used to compare the simulation results with the experimental ones. The modeling and experimental results showed an increase in silencer chamber volume results in a reduction of recorded pressure within the silencer chamber.

Parallel computing assigns the computing model to different processors on different devices and implements it simultaneously. Accordingly, it has broad applications in the numerical simulation of geotechnical engineering and underground engineering, of which models are always large-scale. With parallel computing, the computing time or the memory requirements will be reduced by splitting the original domain of the numerical model into many subdomains, which is thus named as the domain decomposition method. In this study, a cubic and equal volume domain decomposition strategy was utilized to realize the parallel computing on the distributed memory system of four-dimensional lattice spring model (4D-LSM) based on the message passing interface. With a more efficient communication strategy introduced, this study aimed at operating an one-billion-particle model on a supercomputer platform. The preprocessing procedure of the parallelized 4D-LSM was restructured and the particle generation strategy suitable for the supercomputer platform was employed to minimize the time consumption in preprocessing and calculation. On this basis, numerical calculations were performed on TianHe-3 prototype E class supercomputer at the National Supercomputer Center in Tianjin. Two fieldscale three-dimensional blasting wave propagation models were carried out, of which the numerical results verify the computing power and the advantage of the parallelized 4D-LSM in the simulation of large-scale three-dimension models. Subsequently, the time complexity and spatial complexity of 4D-LSM and other particle discrete element methods were analyzed.
