“…However, 5% TiN composites do not exhibit good agreement with other methods. This is due to the presence of relatively more porosity (Figure 1), which has not been considered in any of the above theories (Equations (7)- (15)). Convective and radiative heat transfer losses are neglected which are also affect the thermal conductivity of composites at high temperature.…”

Finite element modelling (FEM) is performed on AlN-TiN composites. The structure-property relationships are studied for 5 and 10 vol.% TiN composites in view of thermal and thermo-mechanical properties. Thermal stresses are simulated at various temperatures for the 5 and 10% TiN samples in homogeneous and heterogeneous temperature environments. It is found that compressive stresses are associated with the microstructure and these stresses are largest at the interface of the AlN-TiN phases. In addition, thermal strains are simulated at various temperatures for both the compositions. Thermal conductivity and thermal expansion coefficient are estimated using FEM and compared with other known analytical methods.

“…To this end, micromechanical finite element models have been used to understand the local mechanics and mechanisms governing the macroscopic behavior of heterogeneous materials. [34][35][36][37][38][39] These models provided some good information on the overall behavior of the heterogeneous materials based on the known properties of their constituents and the detailed interactions among them. Still, most of the studies did not consider the ultimate ductile failure of DP steels, and only a few examined the failure of these complex steels by developing phenomenological failure criteria for prescribed failure mode and intentional critical loading planes.…”

“…Still, most of the studies did not consider the ultimate ductile failure of DP steels, and only a few examined the failure of these complex steels by developing phenomenological failure criteria for prescribed failure mode and intentional critical loading planes. [38,39] It is generally accepted that ductile fracture strongly depends on the microstructure, voids, inclusions, and microcracks in the material. [40] Ductile materials typically exhibit localized deformation before final fracture, and many multiscale models have been proposed for use in studying the ductile failure and fracture phenomenon in such materials.…”

The effects of the mechanical properties of the martensite phase on the failure mode and ductility of dual-phase (DP) steels are investigated using a micromechanics-based finite element method. Actual microstructures of DP steels obtained from scanning electron microscopy (SEM) are used as representative volume elements (RVEs) in the finite element calculations. Ductile failure of the RVE is predicted as plastic strain localization during the deformation process. Systematic computations are conducted on the RVE to quantitatively evaluate the influence of the martensite mechanical properties and volume fraction on the macroscopic mechanical properties of DP steels. These properties include the ultimate tensile strength (UTS), ultimate ductility, and failure modes. The computational results show that, as the strength and volume fraction of the martensite phase increase, the UTS of DP steels increases, but the UTS strain and failure strain decrease. In addition, shear-dominant failure modes usually develop for DP steels with lower martensite strengths, whereas split failure modes typically develop for DP steels with higher martensite strengths. The methodology and data presented in this article can be used to tailor DP steel design for its intended purposes and desired properties.

“…Therefore, the study of micromechanics made it possible to predict the material's properties as a function of constituent properties and local conditions [14]. As a result, the optimization of a composite's mechanical properties for different applications is based on the understanding of the relationship between the microstructure and their effects on the composite's macroscopic response to the applied load [15]. Micromechanics of composites include: properties of the constituent materials, reinforcement size and geometry, reinforcement volume fraction, reinforcement-to-matrix interfacial adhesion, and reinforcement spatial distribution [14] [16]- [23].…”

In this study, a numerical representative volume element (RVE) model was used to predict the mechanical properties of a Rice Husk Particulate (RHP)-Epoxy composite for use as an alternative material in non-critical applications. Seven different analytical models Counto, Ishai-Cohen, Halpin-Tsai, Nielsen, Nicolais, Modified Nicolais and Pukanszky were used as comparison tools for the numerical model. RHP-Epoxy biocomposite samples were fabricated with 0%, 10% and 30% RHP volume percentage and the experimental results benchmarked against the numerical and analytical projections. The mechanical properties estimated for 0%, 10% and 30% RHP-Epoxy composites using the numerical and analytical models were in general agreement. Using the analytical models, it was calculated that an increase in volume percentage of RHP to 30% led to continual reduction in elastic Young's modulus and ultimate tensile strength of the composite. The numerical RVE models also predicted a similar trend between filler volume percentage and material properties. These projections were consistent with the experimental results whereby a 10% increase in RHP content led to 15% and 20% decrease in yield stress and tensile strength, but had no effect on the composite's elastic property. Further increase in RHP volume percentage to 30% resulted in 8%, 21% and 28% reduction in Young's modulus, yield stress and tensile strength, respectively. Overall, the results of this study suggest that RHP can be used to reduce the composite raw material costs by replacing the more expensive polymer content with agricultural waste products with limited compromise to the composite's mechanical properties.
