“…Numerical homogenization and representative volume elements (RVEs) are used to model composites’ effective elastic, thermal, and thermoelastic properties. This methodology allows for the preservation of fiber–matrix interactions and the predicted effective properties of blends, which can be further validated with experimental data [ 130 ].…”

Initiatives to reduce plastic waste are currently under development worldwide. As a part of it, the European Union and private and public organizations in several countries are designing and implementing regulations for single-use plastics. For example, by 2030, plastic packaging and food containers must be reusable or recyclable. In another approach, researchers are developing biopolymers using biodegradable thermoplastics, such as polyhydroxyalkanoates (PHAs), to replace fossil derivatives. However, their production capacity, high production costs, and poor mechanical properties hinder the usability of these biopolymers. To overcome these limitations, biomaterials reinforced with natural fibers are acquiring more relevance as the world of bioplastics production is increasing. This review presents an overview of PHA–vegetal fiber composites, the effects of the fiber type, and the production method’s impact on the mechanical, thermal, barrier properties, and biodegradability, all relevant for biopackaging. To acknowledge the behaviors and trends of the biomaterials reinforcement field, we searched for granted patents focusing on bio-packaging applications and gained insight into current industry developments and contributions.

“…Recently researchers (Patil et al, 2017;Deierling and Zhupanska, 2018;Gopinath and Batra, 2018;Zhu et al, 2018;Zhou et al, 2020;Mukhopadhyay et al, 2016) investigated the effective properties of composites using methods based on homogenization and RVE/unit cell technique. Patil et al (2017) predicted the effective properties of heterogeneous materials by applying the extended as well as multiscale FE method (XFEM and MsFEM) in which the particles and voids were incorporated into the matrix.…”

“…They have considered three types of voids and particles incorporated in matrix such as voids, hard particles as well as both voids and hard particles, and determined the effective properties by applying PBCs to the RVE. Deierling and Zhupanska (2018) developed the FE-and RVE-based models to estimate the effective thermoelastic properties of the spatial variation of graded multiphase particulate reinforced composites. To generate the high-resolution with spatial variation of graded microstructures of the constituents of composites, the effective particle packing algorithms were used.…”

“…However, the generation of different RVEs for different integration points at the macro scale and performing a two-scale simulation could lead to prohibitive time of computations. The application of the FE-based homogenization for the FGMs has been discussed in works of Shabana and Noda (2008) and Deierling and Zhupanska (2018). The other way is to use the mean field homogenization approaches among which the most popular is the Mori–Tanaka (M–T) method (Benveniste, 1987; Mori and Tanaka, 1973).…”

Purpose The purpose of this study is to develop a homogenization approach that ensures both high accuracy and time-efficient solution for elastic-plastic functionally graded composites. Design/methodology/approach The paper presents a novel two-stage hybrid homogenization approach that combines advantages of the mean field homogenization and homogenization based on the finite element method (FEM). The groundbreaking nature of the developed approach is associated with division of the hybrid homogenization procedure into two stages, which allows to very efficiently determine the solution for arbitrary volume fraction of the reinforcement. This paper concerns also on modelling of composites with randomly distributed prolate and oblate particles. For this purpose, the hybrid homogenization was implemented in the framework of the discrete orientation averaging procedure involving pseudo-grain discretization method. Findings Agreement between the results obtained using the proposed approach and the standard FEM-based homogenization is very good (up to the volume fraction of 0.3). Originality/value The proposed two-stage homogenization approach allows to obtain the solution for materials with arbitrary volume fraction of the reinforcement very efficiently; therefore, it is highly beneficial for the two-scale modeling of nonlinear functionally graded materials and structures.
