Stress distributions and stress concentration factors in a simple beam with a circular hole subjected to constant bending momentMesut UyanerSecil Erim
The stresses within a cantilever beam are known, so it’s a simple matter to predict (using, e.g., the Markaki and Clyne formulation) the applied load at which the peak stress within the system will reach the yield stress of the fiber material. The maximum local stress will occur at ...
The calculation of the NS for simple structural elements can be performed by applying the principles of structural mechanics, assuming a linear elastic behavior. Fig. 20 illustrates the determination of the NS in a beam component, with the assumption that the localized stress effects of the weld ...
Cantilever beam tests carried out on a freshwater ice cover showed that introducing stress relief holes at the root of the beam increased flexural strength, as determined from simple beam theory, by 1 4 to 1 3, compared to conventional cantilever beams. Finite element analysis confirmed the exist...
The paper presents the information necessary to perform and validate finite element weld residual stress simulations in both the simple austenitic beam and the more complex ferritic beam, and provides performance measures for the austenitic beam problem. 展开 关键词: Simulation Stress Finite element ...
Curved nanostructures with both homogeneous (nanorings, nanotubes) and variable (nanospirals) radii of curvature spontaneously assembled when grain coalescence was induced in electron-beam-patterned thin-film bilayers. In addition, large stresses could be induced after deposition and patterning and only ...
The steel plate is connected with the steel beam by bolts, the steel beam and the ground groove are fixed by anchor bolts to ensure that the load and the compression rod are always in a straight line and the eccentricity can be avoided. The loading device is shown in Fig. 2. Figure 2...
The hanger main body portion has a plurality of cut-out areas formed by intersecting cross- beams with a continuous main arced counter stress cross-beam thereacross. In this manner, all of the stresses acting on the hanger are distributed evently throughout the arc formed by the continuous ...
According to the clamping way of the workpiece, we take the half of the workpiece as a simple beam for force analysis, as shown in Figure 2(b) and (d). Figure 2 Workpiece clamping and deformation force diagram Full size image The deformation force of the workpiece is caused by the ...
In order to calibrate the different simulators the availability of analytical techniques with a sufficient resolution is essential. Very promising stress characterization techniques are micro-Raman spectroscopy and electron-beam based methods. View chapter Chapter Yield criteria for isotropic materials ...
