... beam theory. One of the basic assumptions used in the Code Case and in this derivation is that there is no ovalization from torsion. Thus, the Flexibility Factor for the torsional displacement (twisting) of an elbow is one. Results show that an exact solution for Flexibility Factors based...

... analytical model, which considers the torsion caused by the differences between the winding angles of the inner and outer steel wire layers, has been proposed using structural mechanics. The model includes an inner high density polyethylene (HDPE) layer, an inner steel wire layer, an outer steel wire layer...

...Zengliang Gao; Tianwen Zhao; Xiaogui Wang; Yanyao Jiang Uniaxial, torsion, and axial-torsion fatigue experiments were conducted on a pressure vessel steel, 16MnR, in ambient air. The uniaxial experiments were conducted using solid cylindrical specimens. Axial-torsion experiments employed thin...

..., it is demonstrated that the mean shear stress has very little influence on the fatigue limit of a notch-free ductile material under cyclic torsional loading. When the torque versus angle of rotation stabilizes after only a few cycles, the alternating stress will become a constant regardless of the value...

...Amran Bin Ayob The objective of the study is to determine the effect of diameter/thickness (D/T) ratio on the interaction of axial force, bending moment, torsion and internal pressure in plain pipes. The Tresca and von Mises criteria are used to determine the first yield behavior of pipes when...

...J. A. Wang; K. C. Liu A new method, designated as Spiral Notch Torsion Test (SNTT), is developed recently to measure the intrinsic fracture toughness K IC of structural materials. The SNTT overcomes many of the limitations inherent in traditional techniques and makes it possible to standardize...
