“…VPPs find implementation as robotic grippers [22] or medical mattresses [23]. As for dampers, VPPs exists as linear dampers [24], torsional dampers [25] and cores in sandwich beams [20]. A typical linear VPP damper is shown in Fig.…”

Blast mitigation continues to be a popular field of research when military vehicles are concerned. The main problem is coping with the vehicle global motion consequences following an explosion. The paper presents a potential application of the linear vacuum packed particle (VPP) damper as a supplementation for a viscous shock absorber in a traditional blast mitigation seat design. The paper also presents field test results for the underbelly blast explosion, comparing them to the laboratory tests carried out on the impact bench. To collect accelerations, the anthropomorphic test device, i.e. the Hybrid III dummy, was used. A set of numerical simulations of the modified blast mitigation seat with the additional VPP linear damper were revealed. The VPP damper was modeled according to the Johnson-Cook model of viscoplasticity. The Hertzian contact theory was adopted to model the contact between the vehicle and the ground. The reduction of the dynamic response index (DRI) in the case of the VPP damper application was also proved.

“…It is a base for numerous types of "smart" grippers, which enable us to grab and move elements with non-regular surface [14]. Moreover, this "material" can be utilized as an active element of adjustable dampers, which are competitive to MR or ERF dampers [9,15,16]. The biggest advantage of those structures is a relatively low manufacturing and operating cost.…”

This paper concerns the problem of empirical investigation and mathematical modelling of a novel controllable damper using Vacuum Packed Particles. Vacuum Packed Particles tend to be placed among the group of so-called 'smart structures'. The macroscopic mechanical features of such structures can be controlled by the partial vacuum parameter. The authors consider an application of Bouc-Wen model in order to represent the dynamic behaviour of the investigated device. The verification of the model response with experimental data is discussed. The Bouc-Wen model parameters identification is described.

“…The most effective way to dampen unfavourable vibrations is to use damping devices. Modern solutions facilitate controlled properties of vibration damping devices, and vacuumpacked particles are a special case, examples of which are presented in the works [7,8].…”

“…The last application of vacuum-packed particles was the work of Rodak et al [8] which presents the use of a linear damper as a supplementation for a viscous shock absorber in blast mitigation seat in military armoured vehicles. The linear VPP damper and the viscous damper were installed parallelly.…”

In modern mechanical engineering, vibrations play an extremely important role. Even with small variable loads, the lack of properly conducted analysis of vibrations or dynamic stability may lead to irreversible damage. The use of modern solutions such as the implementation of piezoceramic elements, appropriately selected damping, specially designed heads in loaded slender systems or heat treatment resulting in enhancement of internal structure of the material allows one to design modern and durable structures.Vibrations of molecules propagating in an elastic medium create mechanical waves. The analysis of this phenomenon in continuous media allows one to produce modern structures such as phononic crystals or metamaterials, which, thanks to their unique properties (the presence of a phononic band gap) leads to the design of devices that control the way energy is transferred in an elastic media. This creates the possibility of manufacturing devices such as acoustic diodes, waveguides, selective filters, mechanical wave mirrors, and many others.This Special Section of BPAST will be devoted mainly to the selected papers presented at the International Conference "Applications of Physics in Mechanical and Materials Engineering APMME 2021" organized online in 2021 by Częstochowa University of Technology. The conference was attended by over a hundred participants from research centers located in such countries as Bulgaria,
