Mathematical modeling of damage in unidirectional composites [PDF]

A review of some approximate analytical models for damaged, fiber reinforced composite materials is presented. Using the classical shear lag stress displacement assumption, solutions are presented for a unidirectional laminate containing a notch, a ...

Comment on "Minimal size of a barchan dune"

, 2007
It is now an accepted fact that the size at which dunes form from a flat sand bed as well as their `minimal size' scales on the flux saturation length.

Paracrine Factor Local Gradient‐Generating System for Engineering Perfusable Vascularized Hepatocyte Tissues with Perfusion‐Induced Proliferation

Advanced Healthcare Materials, EarlyView.
A paracrine factor local gradient (PFLG)‐generating system enables microvessel penetration across 3D hepatocyte tissues. The resulting vascularized constructs recapitulate hepatic sinusoidal hepatocyte—endothelial contact architecture and enhance hepatic functions in vitro.

Effect of Stiffeners on Shear Lag in Steel Box Girders

Al-Khawarizmi Engineering Journal, 2012
This paper studies the effects of stiffeners on shear lag in steel box girders with stiffened flanges. A three-dimensional linear finite element analysis using STAAD.Pro V8i program has been employed to evaluate and determine the actual top flange stress

Melt Electrowriting High Resolution Poly(ethylene‐co‐vinyl acetate) Scaffolds for Soft Tissue Engineering

Advanced Healthcare Materials, EarlyView.
This work pioneers melt electrowriting (MEW) of polyethylene vinyl acetate (PEVA) to fabricate ultra‐compliant, high‐resolution scaffolds. By integrating microscale precision with soft tissue‐like biomechanics, PEVA overcomes stiffness‐driven limitations of conventional MEW polymers, establishing a mechanically biomimetic platform for soft tissue ...

The Concrete Effective Width of a Composite I Girder with Numerous Contact Points as Shear Connectors

Applied Mechanics
Due to the shear strain in the plane of the slab, the parts of the slab remote from the steel beam lag behind the part of the slab located in its proximity. This shear lag effect causes a non-uniform stress distribution across the width of the slab. As a

Supramolecular Engineering of Fluid Pressure in Filamentous Hybrid Double Network Hydrogels for 3D Chondrocyte Culture

Advanced Healthcare Materials, EarlyView.
Inspired by the water‐rich and interconnected biopolymer networks of native load‐bearing tissues, we disclose a connectable design for a hybrid filamentous supramolecular and covalent double network hydrogel generated through in situ photopolymerization.

Behaviour of Shear Stress Distribution in Steel Sections Under Static and Dynamic Loads

Infrastructures
Shear lag is the phenomenon that occurs when a supported slender member undergoes deformation from lateral loading, causing in-plane non-uniform distribution of stresses that results in reducing the member’s minimum strength capacity.

An Estimate of the Isopycnal Diffusion Tensor Based on Particle Statistics [PDF]

, 2010
The quality of eddy ux-gradient parametrizations in models with coarse resolution depends on whether the generated diffusivity is similar to that of reference solutions produced by eddy resolving models.
