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...

Abstraet. Composite material elastic behavior has been studied using many approaches, all of which are based on the concept of a Representative Volume Element (RVE). Most methods accurately estimate effective elastic properties when the ratio of the RVE size to the global structural dimensions, denoted here as ~/, goes to zero. However, many composites are loeally periodic with finite q. The pu...

A three-dimensional (3D) representative volume element (RVE) model was developed for analyzing effective mechanical behavior of fiber-reinforced ceramic matrix composites with imperfect interfaces. In the model, the fiber is assumed to be perfectly elastic until its tensile strength, and the ceramic material is modeled by an elasto-plastic Drucker-Prager constitutive law. The RVE model is then ...

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 present manuscript approaches the mechanical interpretation about volume changes of auxetic metamaterials within a multiscale perspective. kinematic fields resulting from tests were assessed via digital image correlation (DIC). characterization is grounded sound homogenization principles based on representative elements (RVE) at large deformations. main achieved results concern in highlight...

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...
