The hole is shifted to various locations along the transverse axis and two different materials, namely isotropic (steel) and orthotropic (graphite-epoxy), are used as beam material. Stress distribution and stress concentration factors around the hole are determined for each case. In order to ...
By using a computer program especially developed for ex ternally prestressed concrete bridges,the stress variation of external tendons u nder live load in several typical spans of an externally prestressed concrete si mple beam bridge was analyzed.The influences of span depth ratio,the different b ...
THE 1968 AASHO SPECIFICATIONS REQUIRE THAT THE CRITICAL BUCKLING STRESS BE LIMITED BY A FORMULA BASED ON THEORETICAL AND EXPERIMENTAL INVESTIGATIONS OF A SIMPLE BEAM SUBJECTED TO LOADS PRODUCING PURE BENDING. THE PURPOSE IS TO EXAMINE THIS FORMULA TO DETERMINE ITS APPLICABILITY TO HIGHWAY SIGN ...
Very promising stress characterization techniques are micro-Raman spectroscopy and electron-beam based methods.

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...
James Dean, in Comprehensive Composite Materials II, 2018 4.6.3.2 Predicted Onset of Yielding 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 ...
Bone was modeled with 3D beam element and muscle was modeled with spar element. For upper limb muscle modelling, rectus abdominis, trapezius, deltoideus, biceps brachii, triceps brachii muscle and other main muscles were considered. Lower limb muscle was modeled with gastrocenemius, gluteus maximus...
This system has a simple, explicit solution in terms of σ, τ, and V, the value of W on the centerline of the beam. Introducing certain body forces f_x and f_z, we obtain explicit formulas for σ, τ, U, and W valid in the interior of the beam and satisfying any imposed tr...
Comparison of preferred orientation and stress in silver thin films on different substrates using x-ray diffraction Silver thin films were deposited onSiO2and polyethylene naphthalate (PEN) using e-beam evaporation. X-ray diffraction techniques were used to investigate t... Y Zoo,TL Alford - 《...
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...
