Controlling the hazards to facilities caused by detonation waves is a high priority in engineering design. To protect an underground facility, soil can reduce the destructive effects of detonation waves. Soil dynamic characteristics and the area of the destructive zone are affected by shock wave energy. The material at ground zero is impacted by high-intensity stress and forms a crater. To ensure the safety of the facility, the protective soil layers must be sufficiently thick. Therefore, the purpose of this study was to analyze the destructive effects that caused the deformation and destruction of an external protective soil layer. The results of the explosion experiments and the numerical simulation analysis were compared to explore the dynamic characteristics of the soil affected by the shock wave and the crater effects of on-ground explosions. The analysis model adopted an 8-node hexahedral element to create a three-dimensional solid structure model of the fluid-solid interaction. The material failure analysis demonstrated that the detonation wave destabilized the interior of the soil body, and the nearby high-intensity stress was the key factor for material failure. The results can serve as a reference for the design of soil-covering layers that provide explosion hazard control.

Improvised Explosive Devices (IEDs) represent a serious threat to vehicles. These IEDs can partially or fully damage the vehicle and the onboard equipment and, threaten the lives of its crew. To protect against these devices, modifications to specialized vehicles are made in different parts. Among these latter, the present work focuses on the effects of the suspension system on the dynamic response of the vehicle. The behaviour of a McPherson suspension system of a light vehicle is numerically studied in order to optimize the dimensions of selected components. Three models based on different approaches are developed. The first is based on an Arbitrary Lagrangian Eulerian (ALE) formulation with fluid-structure coupling, which gives a more realistic representation of the blast phenomena. However, it needs significant calculation time and computational power. The second is a simplified, purely Lagrangian, model which requires less computational resources but includes several assumptions. The third model is based on a meta-modelling approach. This latter is used to optimize the dimensions of selected sub-systems of the vehicle suspension via a genetic optimization algorithm.

“…Although most of these vehicles use wheels with tires to drive on roads and it has several advantages [15], there are also track vehicles, which use rubber tracks for driving. It is obvious that using rubber in the case of a military demining vehicle is not possible [16][17][18][19][20].…”

Even today, there are countries that are affected by war and its pitfalls. The authors have decided to present a part of the accompanying research results in this article. This research precedes the design of a demining machine Božena 5. The main goal of the authors’ activities was to design optimal material and geometry for a track of this machine. To achieve this goal, the authors conducted research to evaluate the microstructure of the material S960QL and its tribological lifetime. As the track of the demining machine is a welded component, the authors also investigated the influence of different welding technologies on the given parameters. The tribological research was performed on an original test device. The obtained results show that welding joints have the typical microstructure of martensitic high-strength steels and that mechanical properties can be influenced by individual welding technologies. Meanwhile, the use of the electron beam significantly extends the adhesive-abrasive lifespan compared with the MAG (metal active gas) conventional method as well as to the base material. It is interesting that the absolute value of material loss over time reached the identity for both the laser beam and the electron beam. The obtained data provide changes to apply the proposed material for the production of the solved component.
