The purpose of this study is to investigate bending moment and the axial load capacity of a pressurized pipe suffering from a through-wall circumferential crack repaired by a composite sleeve. The three-dimensional finite element method (FEM) was adopted to compute the results, and the failure assessment diagram (FAD) was employed to investigate the failure behavior of the repaired pipe. The fi...

In this paper, the equation of motion of an elastic 2 DoF wing model has been derived using Lagrange's method. The aerodynamic loads on the wing were calculated via the Strip-Theory and the effect of compressibility was included. Wing deflections due to bending and twist motions were determined using the Assume-Mode method. The aeroelastic equations were solved numerically using the V-g method....

Fourteen composite honeycomb sandwich panels were tested to failure under compressive loading. The test specimens included panels with both eight and twenty-four ply graphite-bismaleimide composite facesheets and both titanium and graphite-polyimide core materials. The panels were designed to have the load introduced through fasteners attached to pairs of steel angles on the ends of the panels ...

where M is the bending moment, F is the force applied, and D is the distance from the point of force application to the axis of rotation (moment arm length). This is perhaps best depicted in Figure 11.1. Using this equation, one can determine the bending moment applied in any given clinical circumstance. The bending moment has substantial clinical significance. The application of a bending mome...

this paper deals with the solution of a column with balcony loads. it is intended to determine the expressions for deflections and bending moments of the sections of a column under the action of transmitted loads from a balcony loaded at its free end by a force «p» and rigidly connected to the column somewhere between its ends. the action of this load on the column is equivalent to that of the ...

Removal of large segments of the apical part of the stipe of Coprinus cinereus (extending to about half its length) affected neither the ability of the stipe to show gravitropic bending nor its ability to compensate the curvature so induced and adjust to the vertical. However, gravitropic reaction time was directly proportional to the amount of stipe removed. Application of lateral loads of up ...

This paper addresses the boundary control for flutter suppression of a flexible wing, both in bending and twisting displacements, under unsteady aerodynamic loads. The wing is modeled by a distributed parameter system described as two coupled partial differential equations. The problem is tackled in the framework of semigroup theory, and a Lyapunov-based stability analysis is carried out to ass...
