Mechanical characterization of protein molecules has played a role on gaining insight into the biological functions of proteins, because some proteins perform the mechanical function. Here, we present the mesoscopic model of biological protein materials composed of protein crystals prescribed by Go potential for characterization of elastic behavior of protein materials. Specifically, we conside...

A representative volume element (RVE) based multi-scale method is proposed to investigate the mechanism of fatigue crack propagation by molecular dynamics (MD) and extended finite methods(XFEM) in this study. An atomic model carbon steel plate built study behavior at micro scale MD method. Then RVE for should be fitting data which was obtained from result with Paris law model. Moreover, effect ...

The statistical significance of grain-scale lattice rotation results is analysed. case the Ref. [1] specifically considered. Quantitative elements theory statistics are applied to determine precisions (standard errors) and size representative volume element (RVE), in terms minimal number grains necessary obtain results. It shown that defined sufficient precision support conclusions made. In gen...

A three-dimensional micromechanical finite element model is developed to study the viscoelastic behavior of the silica nanoparticle/polyimide nanocomposites. The representative volume element (RVE) of the model consists of three phases including silica nanoparticle, polyimide matrix and interphase which surrounds the nanoparticle. The interphase region is created due to the interaction between ...

Glass fibers reinforcing composites (GFRC) are the most common industrial materials due to their low weight and superior strength. Microstructure modeling provides a practical approach for predicting behavior of composite based on constituent's property. The mechanical properties play significant role in various applications such as aviation, marines, vehicles industries. In this study, microst...

The paper reports on finite element method (FEM) analysis of Cu–SiC composites behaviour under cyclic loading conditions. In order to emphasise the influence of materials description on following results, there were two hardening rules used to describe the plastic behaviour of the matrix: (a) simple isotropic and (b) combined isotropic-kinematic. Reinforcing ceramics was assumed to be perfectly...

The effect of the clusterization on effective properties a composite material reinforced by MXene or graphene platelets is studied using finite element method with periodic representative volume (RVE). A hybrid 2D/3D mesh used to reduce computational complexity numerical model. Several realizations an RVE were generated increasing fractions inclusions, resulting in progressive platelets. Numeri...

This paper presents a computational framework that generates ensemble predictive mechanics models with uncertainty quantification (UQ). We first develop causal discovery algorithm to infer relations among time-history data measured during each representative volume element (RVE) simulation through directed acyclic graph. With multiple plausible sets of relationships estimated from RVE simulatio...

Carbon nanotubes (CNTs) possess extremely high stiffness, strength and resilience, and may provide ultimate reinforcing materials for the development of nano composites. In this paper, the effective material properties of CNT-based composites are evaluated using a square representative volume element (RVE) based on the continuum mechanics and with the finite element method (FEM).
