“…In particular, all loss parameters, loss modulus (E″) and loss tangent factor d tan ( ( )), predicted by the PFC-MPCD method can demonstrate at least one peak location. These observations are in good agreement with the real solid behavior suggested by [21] and experimental evidence that can be found in [25][26][27][28][29][30][31]. The peak location in loss modulus (E″) parameter also indicates the information on the suitable working frequency where the energy is most dissipated in damping material design.…”

“…In particular, all results predicted by PFC-MPCD method are agreeing with numerous experimental observations which can be found in [25,26] for shear and young modulus, which are proportional to storage modulus, in In-Sn and Pb-Sn as well as for loss angle in some alloys [27] which is related to loss tangent factor. Besides, this consistency is even more pronounced in rubber [28][29][30] and in elastomer [31]. This is in contrast to the results obtained from PFC-PCD prediction in figure 7(b) where all complex moduli parameters monotonically increased with increasing frequency without peaks location for loss modulus (E″) and loss tangent factor d tan ( ( )) as well as without the certain frequency value which allows storage modulus E′ to become constant.…”

Damping materials have been used in numerous engineering applications. The important property that plays a key role in this type of material is a damping capacity which is related to mechanicalhysteresis behavior of viscoelasticity. During the last decade, the phase-field-crystal (PFC) model has emerged as a robust tool to predict various material phenomena. This density-functional-type model has the advantage over a conventional phase-field model in terms of atomistic resolution and molecular dynamics in terms of computational expense. In this work, we propose a method to predict mechanical-hysteresis behavior and its related complex moduli parameters using a modifiedpressure-controlled dynamics (MPCD) equation incorporating with the PFC model, denoted as PFC-MPCD method, in a three-dimensional solid structure. We modify the previously proposed pressurecontrolled dynamics (PCD) equation by introducing the pressure-time derivative term which allows us to produce the results consistent with the standard linear solid model (SLS) at the broader frequency range. We apply sinusoidal pressure oscillation and compare the results predicted by both models. The results demonstrate that mechanical-hysteresis behavior and complex moduli parameters predicted by PFC-MPCD method are in good agreement with those of SLS model and consistent with numerous experimental observations whereas the results produced by original PCD equation tends to exhibit inaccurate results at the very frequency. We expect that this new PFC-MPCD method can be extended to a more complex system and still be capable to exhibit the accurate mechanical-hysteresis behavior and complex moduli parameters which results in predicting more reliable damping capacity parameter in damping material design. computational technique that incorporates microstructures which influences the material properties and can reproduce a correct mechanical-hysteresis behavior.During the last decade, the phase-field-crystal (PFC) method has appeared as a promising tool to investigate numerous material phenomena. In the PFC model, its free energy functional is minimized by periodic density field which provides elastic effects and microstructural features e.g. multiple crystal orientations, grain boundary and dislocations which is more appealing than conventional phase field (PF) model in terms of self-consistency. Moreover, this method is restricted to operate on diffusive time-scales which give an advantage over molecular dynamics (MD) in terms of computational expense. The PFC model was first introduced by Elder et al [1] which its free energy functional was minimized by periodic function that found in many physical systems even in crystalline structure. This model that incorporated elastic and plastic properties [2] was used to study various range of material phenomena such as phase transformation [3,4], topological defect dynamics such as crack [2,5], elasticity [6-8] to plasticity [9,10]. This method could also be used to model microstructural defects such as vacancy [11], grain...

“…The results are used to determine a master curve from the frequency and temperature measurements by using the TTS approach as described before. The shift factors are calculated by horizontally shifting the storage modulus curves to gain the best fitting continuation of the surrounding curves as described in [33]. To characterize the damping behavior, the system's loss factor tanδ for forced bending vibrations is defined as the ratio of the homogenized loss to storage modulus.…”

“…It should also be mentioned that the viscoelastic interlayer can significantly reduce the bending stiffness of the laminate, but increase the damping and therefore a trade-off between damping and stiffness must be considered. The influence of different laminate lay-ups on the stiffness and damping behavior in 3PB configuration was shown in [33].…”

The investigated hybrid carbon fiber reinforced plastics-elastomer-metal laminates (HyCEML) offer the potential of tailored structural materials with adaptable damping properties. Conventional fiber metal laminates, like glass laminate aluminum reinforced epoxy are already widely spread in the aviation industry owing to their outstanding fatigue behavior. By integrating an elastomeric interlayer, the glass fibers can be substituted by carbon fibers and damping properties of these laminates can be adjusted. The viscoelastic interlayer dissipates energy within the laminate by inducing shear strain during bending, which is commonly known as constrained layer damping. The aim of this paper is the description of the vibration and damping behavior of HyCEML over a wide temperature and frequency range by using different test methods. Dynamic mechanical analysis is used for the individual polymeric constituents and coupon specimens and modal analysis is used with different specimen geometries up to a component sized panel. In addition, analytical and numerical approaches complement the experiments and lead to a deeper understanding of the vibration and damping behavior. Owing to the high damping, already at frequencies of 5 kHz only running waves can be detected for the investigated panel size. The discussion of different test methods helps to identify material and wavelength dependent effects, but also possible adverse effects of certain methods.

Solid crosslinked biopolymers made by inverse vulcanization of soybean (PSB) or sunflower (PSF) oil with sulfur are characterized and tested to decontaminate water from hydrocarbons (HC): gasoline, diesel, two lubricant oils, and water/gasoline emulsion. The physicochemical structure of the biopolymers is studied by FTIR spectroscopy, Differential scanning calorimetry, contact angle measurement, and mechanical testing. Also, the morphological structure is analyzed by scanning electron microscopy. Moreover, the polymer decontamination capability and reusability are tested gravimetrically. Both biopolymers are formed by CS bonds, and their elastic behavior dominates. However, PSF is more hydrophilic, has a larger amount of free sulfur and a less compact structure, and also sorbs ca. 60% more HC than PSB. The results indicate that the unsaturated feedstock has a strong effect on the polymer structure and the capacity to remediate contaminated water or solids. Also, both materials can be reused to remediate water for more than five consecutive cycles. In addition, inverse vulcanization of oils and sulfur is an ecological way of obtaining environmentally‐improved materials with great potential and applications, providing a complete atomic economy and high performance to remediate water from water/HCs dispersed and, more importantly, from water/gasoline emulsions.
