Stress distributions and stress concentration factors in a simple beam with a circular hole subjected to constant bending momentMesut UyanerSecil Erim
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 ...
Residual Stress Distribution in TiN Thin Films with Fiber Texture Measured by Grazing Incidence and Scattering Vector X-Ray Methods Titanium nitride (TiN) thin films with the thickness of 0.1, 0.2, 0.5, 1.0, 2.0 and 4.0μm were coated on a carbon steel substrate by the ion beam mixing m....
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 ...
A relation for the bending stress in the 90° layer as a function of its coordinate in the thickness direction z is obtained from simple beam theory: (3)σb,1*90z=FL/2−dzE22E1I0+E2I90forz∈12t0,12t0+t90 where d is the longitudinal distance between the crack plane and the vertic...
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...
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 causes the rock around a portion of the wellbore to fail in compression. For the simple case of a vertical well drilled when Sv is a principal stress, this leads to the occurrence of stress-induced borehole breakouts that form at the azimuth of the minimum horizontal compressive stress....
