Abstract This paper focuses on the development of a surrogate model to predict macroscopic elastic properties polymer composites doped with spherical particles. To this aim, polynomial chaos expansion based Kriging metamodeling technique has been developed. The training experimental design is constructed through dataset numerical representative volume elements (RVEs) considering randomly disper...

In the analysis of textile-reinforced shell structures full-scale models are often impractical due to complex nature meso-structure. The structure is assumed be globally periodic which allows definition a representative volume element (RVE). this contribution, RVE embedded within first-order homogenisation framework, where meso-to-macro transition governed by Hill-Mandel condition. coupled mult...

A novel micromechanics based damage model is proposed to address failure mechanism of defected solids with randomly distributed penny-shaped cohesive micro-cracks (Barenblatt–Dugdale type). Energy release contribution to the material damage process is estimated in a representative volume element (RVE) under macro hydrostatic stress state. Macro-constitutive relations of RVE are derived via self...

Abstract Two methods used to construct a microstructural representative volume element (RVE) were evaluated for their accuracy when in crystal plasticity-based finite (CP-FE) model. The RVE-based CP-FE model has been shown accurately predict the complete tensile stress–strain response of Ti–6Al–4V alloy manufactured by laser powder bed fusion. Each method utilized different image-based techniqu...

Biopolymer gels, such as those made out of fibrin or collagen, are widely used in tissue engineering applications and biomedical research. Moreover, naturally assembles into gels vivo during wound healing thrombus formation. Macroscale biopolymer gel mechanics dictated by the microscale fiber network. Hence, accurate description can be achieved using representative volume elements (RVE) that ex...

In this paper, the yield behavior of closed-cell foams under multiaxial load conditions is investigated via finite element analysis on representative volume (RVE) scale by using regular Kelvin RVE and random models RVE, respectively. Several different definitions are considered in study. By benchmarking simulations with experimental data literature, it shown that elastic energy criterion to be ...

This paper gives an intuitive numerical multi-scale method to estimate damping in anisotropic viscoelastic hybrid composite structures using finite element analysis. Different CFRP-R (CFRP with Rubber) architectures, both microstructural and macrostructural, are studied compared order maximize but also minimize rigidity loss. Homogenization by virtual DMA frequency domain is performed on repres...

The model proposed simulates the effective material behavior of calcified hydrogels using multiscale finite element method (FEM). To this end, representative volume elements (RVEs) are generated to depict biphasic microstructure consisting organic hydrogel and inorganic calcium phosphate. choice matrix influences type agglomeration phase thus dictates geometry RVE. Most commonly, appears in for...

Strain-rate-dependent mechanical properties and impact performance of manufactured epoxy-based nanocomposites are investigated. As reinforcements, fumed silica (FS) halloysite nanotube (HNT) used alongside Albipox 1000 Nanopox F700. First, the internal structures composites visualised using scanning electron microscopy (SEM). To identify strain-rate-dependent properties, three-point bend tests ...
