The swelling of natural fibers is often a drawback when considering structural applications biocomposites. However, this mechanism represents the key towards development Hygromorph BioComposites (HBC). This investigation aims to understand hydroexpansion 3D-printed continuous flax-fiber reinforced biocomposites and effect matrix stiffness. Four flax fiber-based were selected with wide range Wat...

3D forced vibrations of two-layered plates under an influence periodic in time tangential actions were studied. An asymptotic solution the corresponding problem theory elasticity was obtained. The problem, particular, models seismic on base-foundation structures. All components stress tensor and displacement vector determined. It is shown, that among these quantities ones play leading role. Cas...

Mineralized collagen microfibrils in human bone provide its mechanical properties (stiffness, elasticity, ductility, energy dissipation and strength). However, detailed 3D finite element models describing the mechanical behavior of the mineralized collagen microfibrils are still lacking. In the current work, we developed a 3D finite element model of the mineralized collagen microfibril that inc...

This review compiles information regarding the use of alginate, and in particular alginate hydrogels, in culturing cells in 3D. Knowledge of alginate chemical structure and functionality are shown to be important parameters in design of alginate-based matrices for cell culture. Gel elasticity as well as hydrogel stability can be impacted by the type of alginate used, its concentration, the choi...

In native states, animal cells of many types are supported by a fibrous network that forms the main structural component of the ECM. Mechanical interactions between cells and the 3D ECM critically regulate cell function, including growth and migration. However, the physical mechanism that governs the cell interaction with fibrous 3D ECM is still not known. In this article, we present single-cel...

background: different postdesigns and materials are available; however, no consensus exists regarding superiority for stress distribution. the aim of this study was to evaluate the effect of design and material of post with or without ferrule on stress distribution using finite element analysis. materials and methods: a total of 12 three‑dimensional (3d) axisymmetric models of postretained cent...
