Shear Lag in Stiffened Box Girders
Journal of the Structural Division, 1970METHODS FOR THE ANALYSIS OF SHEAR LAG IN WIDE FLANGES ARE REVIEWED AND A TREATMENT IS PRESENTED WHICH INCORPORATES THE EFFECT OF THE WEB UPON THE STRESS DISTRIBUTION IN THE STIFFENED FLANGE OF A BOX GIRDER BY REPLACING THE WEB WITH AN EDGE STIFFENER ON THE FLANGE. ATTENTION IS DRAWN TO THE EFFECT OF SEVERE SHEAR LAG IN THE CURVATURE AND DISPLACED SHAPE

Solution of Nonlinear Shear Lag Problems
Journal of the Structural Division, 1963The governing differential equation for the plane stress problem of a nonlinear material and complete transverse rigidity is derived. Involving a stress function, it is applied in non-dimensionalized, finite difference form to two simply-supported cases of flanged beams having parabolic stress-strain relations. Results are given in the form of charts.

Strain Relaxation in CVD Graphene: Wrinkling with Shear Lag
Nano Letters, 2015We measure uniaxial strain fields in the vicinity of edges and wrinkles in graphene prepared by chemical vapor deposition (CVD), by combining microscopy techniques and local vibrational characterization. These strain fields have magnitudes of several tenths of a percent and extend across micrometer distances.

Journal of Structural Engineering, 1991
The problem of negative shear lag in a cantilever beam subjected to a uniform load is explained in nonmathematical terms. In essence, the problem is one of two components (uniform-load component and concentrated reaction component), each of which is subjected to positive shear lag, being combined such that negative shear lag is produced.

Negative Shear Lag in Flanges of Plated Structures
Journal of Structural Engineering, 1991Negative shear lag is not a particularly exceptional phenomenon but an effect that can occur at a wide variety of arrangements of plated structures with a considerable degree of significance. A description of features of the negative-shear-lag phenomenon is the main objective of this paper.

Shear lag in composite steel concrete beams
2018 1st International Scientific Conference of Engineering Sciences - 3rd Scientific Conference of Engineering Science (ISCES), 2018In order to estimate the flexural rigidity of a composite steel concrete beam, it is necessary to study the shear lag phenomenon, which plays an important role in the distribution of the normal bending stresses at the concrete slab of the composite beam. In this paper, a nonlinear three-dimensional finite element analysis is employed to study shear lag

Shear Lag And Beam Theories For Structures
2004Dynamic problems are solved using beam theory and shear lag approximations, and also FEM. For a laminated plate incorporating through-thickness fibers, highlights are: 1) Inertia complicates the fiber pullout problem considerably. 2) Disturbances propagate along frictionally coupled fibers at less than the bar wave speed.

Composites Science and Technology, 2012
Abstract The standard shear lag theory for elastic aligned short-fibre composites is extended to allow for a gradient of overall strain. The result is a one-dimensional strain gradient theory of the Toupin–Mindlin type. All parameters are the same as in the standard theory, and in the limits of weak strain gradients, large fibre aspect ratios or low ...

Shear-lag model: corrections, refinements and applications
Tectonophysics, 1997Abstract Since it was developed by Cox [Cox, H.L., 1952. The elasticity and strength of paper and other fibrous materials. Br. J. Appl. Phys. 3, 72–79.], the shear-lag model (SLM) or fiber-loading theory has been widely used by material scientists and structural geologists as a powerful analytical method for analyzing mechanical interactions between ...
