“…The interfacial adhesion between nanocellulose and poly(methyl methacrylate) is systematically examined, and the structural properties and relaxation dynamics of polymer chains near the interface are presented for intentional surface engineering [112]. The effect of stiffened interphase region on the mechanical response of polymer composites is evaluated through multiscale computational analysis for the microscopic failure mechanism [113]. It is expected that the molecular information achieved from nanoengineering can boost the advanced design of nanocomposites in biomedicine.…”

Recent advances in biomedicine largely rely on the development in nanoengineering. As the access to unique properties in biomaterials is not readily available from traditional techniques, the nanoengineering becomes an effective approach for research and development, by which the performance as well as the functionalities of biomaterials has been greatly improved and enriched. This review focuses on the main materials used in biomedicine, including metallic materials, polymers, and nanocomposites, as well as the major applications of nanoengineering in developing biomedical treatments and techniques. Research that provides an in-depth understanding of material properties and efficient enhancement of material performance using molecular dynamics simulations from the nanoengineering perspective are discussed. The advanced techniques which facilitate nanoengineering in biomedical applications are also presented to inspire further improvement in the future. Furthermore, the potential challenges of nanoengineering in biomedicine are evaluated by summarizing concerned issues and possible solutions.

“…As the micromechanical damage mechanism in transversally loaded UD plies is a key aspect of the damage of laminates, researchers have focused on the modeling of these phenomena in recent years (e.g., [5][6][7][8][9][10][11][12][13][14][15][16]). While having insight into the micro-scale damage mechanisms, micromechanical modeling is used for predicting the composite stiffnesses and strengths of FRP based on the known material behavior of the fibers and the matrix.…”

“…To predict the composite behavior, it thus seems relevant to incorporate both the nonlinearity as well as the tension/compression-asymmetry of the pure resin. For modeling these material characteristics, plasticity [7][8][9][10][11]25,26], visco-elasticity [15] and visco-plasticity [12,13,27,28] are used in recent micromechanical simulations of FRP. In addition to the plastic deformations [29,30], nonlinear-elastic and viscous effects also contribute to the stress-strain behavior of polymeric resins [15,28,29].…”

Micromechanical analyses of transversely loaded fiber-reinforced composites are conducted to gain a better understanding of the damage behavior and to predict the composite behavior from known parameters of the fibers and the matrix. Currently, purely elastic material models for the epoxy-based polymeric matrix do not capture the nonlinearity and the tension/compression-asymmetry of the resin’s material behavior. In the present contribution, a purely elastic material model is presented that captures these effects. To this end, a nonlinear-elastic orthotropic material modeling is proposed. Using this matrix material model, finite element-based simulations are performed to predict the composite behavior under transverse tension, transverse compression and shear. Therefore, the composite’s cross-section is modeled by a representative volume element. To evaluate the matrix modeling approach, the simulation results are compared to experimental data and the prediction error is computed. Furthermore, the accuracy of the prediction is compared to that of selected literature models. Compared to both experimental and literature data, the proposed modeling approach gives a good prediction of the composite behavior under matrix-dominated load cases.

“…This difficulty can be overcome by applying the multiscale analysis procedure using the homogenized effective material property. While there has been a tremendous amount of research on multiscale analysis related to structural problems [12][13][14][15], the research on multiscale analysis dealing with magnetic problems is relatively rare.…”

This work presents the multiscale finite element analysis of linear magnetic actuators. Here, the actuators includes unidirectional fiber reinforced magnetic composites as a back-iron core component. The composite is employed in actuators to enhance the magnetic force. However, the direct computation of actuators including heterogeneous composite structures requires high computation cost. To overcome this problem, multiscale computational technique for the analysis of a magnetic actuator is proposed in this work. First, the effective magnetic permeability of the composite is calculated at various fiber volume fractions and orientation angles. For this, the asymptotic homogenization method is applied to the composite unit cell model in microscopic coordinate system. Next, the obtained homogenized effective permeability is utilized for the macroscopic magnetostatic analysis of actuator model. Subsequently, the magnetic force acting on a actuator plunger is calculated using the Maxwell stress tensor method. To validate the accuracy and computational benefit of the proposed multiscale approach, a actuator numerical example is provided. For the accuracy validation, the magnetic force and magnetic field distribution obtained from the proposed multiscale approach are compared with those from the direct calculation. In addition, the computation time consumed for the mutiscale approach and direct calculation is compared to validate the benefit of the proposed analysis process.
