There is an increased demand for cement nanocomposites in the twenty-first century due to their composition, higher strength, high efficiency, and multiscale nature. As carbon nanotubes (CNTs) possess extremely resilience, stiffness, inclusion of small quantities concrete mix makes them a multifunctional material. A molecular level understanding significant capacitate macrolevel properties thes...

Abstract To relate the thermomechanical behaviour and microstructural evolution of heat-assisted incremental sheet forming (SPIF) for Ti–6Al–4 V sheet, multi-scale models based on crystal plasticity finite element model (CPFEM), representative elementary volume (RVE), cellular automaton (CA) were established in this article. An experimental-scale CPFEM was built advance to provide macrograin le...

One of the most famous methods to predict the stiffness of short fiber composites is micromechanical modeling. In this study, a Representative Volume Element (RVE) of a beech wood flour natural composite has been designed and the orientation averaging approach has been utilized to predict its stiffness tensor. The novelty of this work is in finding the proper fiber orientation distribution func...

We examine the microscopic toughening mechanisms and their effect on the macroscopic failure response of heterogeneous adhesives made of stiff particles embedded in a more compliant matrix. The analysis relies on a multi-scale cohesive framework first described in Matouš et al. [Matouš, K., Kulkarni, M., Geubelle, P., 2008. Multiscale cohesive failure modeling of heterogeneous adhesives. Journa...

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 critical state of a granular material made rounded tetrahedral particles is studied through DEM simulations triaxial compressions. A minimum number 7,500 first obtained as the representative volume element (RVE) for present simulations. Then, macroscopic line (CSL) shown to be increasing in (stress, density) space low confining pressures. Such an unexpected behaviour explained by existence ...

We present a computational algorithm for solving the recently developed finite-deformation continuum dislocation dynamics theory of mesoscale plastic deformation single crystals (Starkey et al., 2020). This CDD is based on vector density representation dislocations governed by curl-type transport-reaction equations subjected to divergence-free constraint appropriate density. These evolution are...

To evaluate the relative vaccine effectiveness (rVE) against influenza-related hospitalizations/emergency room (ER) visits, office and cardio-respiratory disease (CRD)-related hospitalizations/ER visits compare all-cause costs associated with two vaccines specifically indicated for older adults (?65 years), adjuvanted (aTIV) high-dose trivalent influenza (TIV-HD), 2018–19 season. A retrospectiv...
