Statistical shear lag model – Unraveling the size effect in hierarchical composites

Acta Biomaterialia, 2015
Numerous experimental and computational studies have established that the hierarchical structures encountered in natural materials, such as the brick-and-mortar structure observed in sea shells, are essential for achieving defect tolerance. Due to this hierarchy, the mechanical properties of natural materials have a different size dependence compared ...

A flexoelectric actuator model with shear-lag and peel stress effects

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2023
Flexoelectric materials are being extensively studied in recent years for potential sensing, actuation, energy harvesting and structural health monitoring applications. However, no analytical model exists in the literature to predict the stress transfer between a flexoelectric transducer and the host structure, considering bonding compliance.

A simplified method for the determination of the effective width due to shear lag effects

Journal of Constructional Steel Research, 1993
Abstract While it is usually assumed in bending theory that plane sections remain plane after loading, this assumption does not hold for short span beams with wide flanges. Shear lag effects cause the stress distribution over the cross-section to be non-linear.

A hand calculation of the shear lag effect in stiffened flange plates

Journal of Constructional Steel Research, 1984
Abstract A method of analysis is presented which enables the effects of shear lag in steel box girders with heavily stiffened flanges to be taken into account quickly and conveniently using hand calculations. The method idealizes the flange as a system of axial load-carrying bar members and shear-carrying sheet members and employs harmonic analysis ...

Shear Lag Analysis and Effective Width of Curved Girder Bridges

Journal of Engineering Mechanics, 1985
The effective width of curved girder bridges is formulated by substituting the flange stress derived from present theory into the equation of effective width definition for the curved girders. The required information in formulating the effective width rule for design of curved girder bridges are provided.

Effect of Skewness on Shear Lag Effect in RC Box-Girder Bridges

2018
This paper deals with 3-D linear elastic finite element analysis of box-girder bridges to study the influence of skewness on the longitudinal stresses and shear lag effect in simply supported box-girder bridges. In the present study, a 20 m span simply supported box-girder bridge with different degrees of skewness varying from 10 to 60° has been ...

Formulas for Shear‐Lag Effect of T‐, I‐ and Box Beams

Journal of Structural Engineering, 1990
Based on an empirical matching of analytical results for stresses in wide flanges obtained using the plane stress elasticity given by Song, simplified empirical formulas and some diagrams for the determination of the shear-lag effect in simple beams under various loading with I, and box cross sections are presented.

Effective number of mega-bracing, in order to minimize shear lag

Structural Engineering and Mechanics, 2013
In this paper, influence of geometric configurations of multi-story bracing on shear lag behaviour of braced tube structures is investigated. The shear lag of 24-, 36- and 72-story braced tube structures are assessed considering all possible configurations of overall X and Chevron bracing types.
