“…By introducing viscosity, the analytical solution offers a simplified model of the permanent deformation of cracked glass. By fitting the magnitude of this viscosity, the theoretical model gives the value of glass deflection 𝜁 𝑐𝑒𝑙,𝑎𝑐𝑡 = 63 mm (see Equation (10)). The corresponding value given via simulation (Model 2, design #67) is 𝑢 max = 65 mm (see Figure 8a).…”

“…To obtain reliable and transferrable experimental data, the creation of stable and repeatable measurement conditions is a must. Thus, many methodological overview publications are available on this topic (e.g., [10,11]. After the careful consideration of the above aspects, we decided to use a well-defined impactor as a representation of a pedestrian's head in our experiments.…”

As was shown in the previous part of the study, windshields are an important part of the passive safety means of modern low-floor trams with an extraordinary effect on pedestrian safety in a pedestrian–tram collisions. Therefore, maximum attention must be paid to the definition of tram windshield characteristics. This article describes a windshield crash test, from which data are obtained to verify the feasibility of the applied computational approaches. A developed analytical model is utilised for a simple description of the energy balance during collision with an illustrative definition of the important parameters of laminated glass as well as their clear physical interpretations. The finite element analysis (FEA) performed in Ansys software using two versions of material definition, namely a simpler (*MAT_ELASTIC with nonlocal failure criterion) and a more complex (*MAT_GLASS with brittle stress-state-dependent failure) material model, which are presented as suitable for obtaining a detailed description of the shattering process of laminated glass, which can also be used effectively in windshield engineering.

“…These initiatives utilize innovative methodologies for the involvement of student populations in prevention and training interventions to promote road safety culture, prevention and knowledge-based action (for example, respect for traffic regulations), and education for sustainable mobility among students [1,2]. The paper highlights the emerging awareness in scientific schools of the potential synergy between road safety and scientific research in the STEM domain (Science, Technology, Engineering, and Mathematics), particularly in the automotive industry [3][4][5]. But in order to act, it is necessary to have a comprehensive understanding of the devices mounted on motor vehicles that directly impact road safety, including brakes and/or dampers [6][7][8].…”

Over the years, the Italian Government has taken significant strides in promoting road safety awareness among the students in high schools to create an awareness of prevention and a consciousness of road safety in the student population. In this context, an agreement was signed between the DICEAM Department of the “Mediterranea” University of Reggio Calabria (Italy) and the “Euclide” Higher Education Institute Bova Marina (Italy) to combine road safety with research science in the Science, Technology, Engineering, and Mathematics (STEM) area. With the primary aim of “knowing in order to act”, the students focused on the multi-physics design of magnetorheological fluid dampers as high-performance devices (simple to design and requiring reduced maintenance) for vehicle suspensions, especially class B vehicles. By combining road safety considerations with multi-physics scientific disciplines, the project seeks to emphasize the importance of prevention and knowledge-based action. The study explores the use of magnetorheological fluid dampers, powered by electric current and magnetic induction distribution with thermal loads, to provide appropriate yield stress for developing damping action with repercussions on the quality of road safety. The paper delves into the basic principles of FEM (Finite Element Method) techniques for analyzing an MR damper from both magnetostatic (the main cause generating the damping effect) and thermal perspectives (thermal effects are strongly influenced by environmental conditions). The analysis of an asymmetrical device, where the damping action relies on an MR fluid strip, reveals the significant influence of magnetic and thermal stresses on the magnetization of individual particles and the overall viscosity of the MR fluid.
