Abatraet--A model predicting the number of prismatic loops dislocation punched at the ends of a cylindrical fiber by thermal mismatch stresses is presented. The longitudinal stress in the fiber is derived as a function of the distance from fiber center using the shear-lag model for the elastic portion of the interface. We show that there is a critical fiber length above which the number of loop...

This paper presents the use of a finite element method (FEM) to analyze shear lag effect due flexure beams with an arbitrary cross-section and homogeneous elastic material. Beams are constrained by most common types supports, such as fixed, pinned, roller. The transverse, concentrated, or distributed loads act on through center cross-section. presented FEM transforms 3D analysis phenomenon into...

In current design procedures, the capacities of single-shear timber connections with lag screws are determined based on their governing failure modes, which assumed to occur independently. this study, capacity and modes evaluated experimentally numerically. Six specimens Red Meranti wood different penetration lengths tested obtain lateral load modes. Nonlinear 3D finite element analyses using A...

This research extends extant literature examining the relationship between IS use and performance. While prior theory has predominantly treated IS use as an antecedent of performance and hypothesized a positive effect of use on performance, this research provides an alternative perspective. Specifically, this paper theorizes that under certain contexts performance can be an antecedent of use an...

Growing living cultures of Escherichia coli bacteria are investigated using real-time in situ rheology and rheoimaging measurements. In the early stages of growth (lag phase) and when subjected to a constant stationary shear, the viscosity slowly increases with the cell's population. As the bacteria reach the exponential phase of growth, the viscosity increases rapidly, with sudden and temporar...
