... This paper discusses a new multi-axial 10.2-cm (4-in.) composite tube test method. This test method is capable of loading a 10.2 cm composite tube by internal pressure, torsion, and tension/compression. The method improves on an older biaxially loaded (internal pressure and axial load) tube...

... stresses for which there is little data. Efforts to determine the interlaminar shear strength of laminated composites have been hampered due to the nonlinear behavior of test specimens and the limitations of current analysis tools. An inexpensive rectangular torsion test specimen was designed to determine...

... A shear deformation theory including residual thermal and moisture effects is developed for the analysis of either symmetric or asymmetric laminates with midplane edge delamination under torsional loading. The theory is based on an assumed displacement field that includes shear deformation...

... An investigation of thermomechanical testing and deformation ehavior of tubular specimens under torsional loading is described. Experimental issues concerning test accuracy and control specific to thermomechanical loadings under a torsional regime are discussed. A series of shear strain...

... Crack growth from notched unidirectional graphite/epoxy tubes subjected to axial, torsional, and combined loading conditions was studied experimentally and theoretically. Tubes with fiber orientations of 2.5, 15, 45, and 87.5° were notched with slots 0.5 cm long, parallel to the tube axis...

... A simple analytical method using a sublaminate approach is introduced to analyze unidirectional and cross-ply laminates under torsion loading. Interlaminar stresses and total energy release rate are evaluated based upon a displacement field that includes shear deformation. Closed-form...

... Discussed are the failure modes observed in a Type 316 stainless steel under biaxial high temperature low cycle fatigue (HTLCF) and creep-fatigue strain cycling. All tests were carried out in air at 621°C (1150°F) using thin-walled tubular type specimens specially designed for axial, torsional...

... Composite bars of rectangular cross sections are loaded in torsion to determine the principal shear moduli and interlaminar strengths. The use of rectangular cross sections greatly simplifies the fabrication of specimens. In [0], [90], and cross-plied laminates, torsional rigidity depends only...

... The process of pultrusion results in a highly anisotropic laminate. When this is twisted, it tends to split along its length. A torsion tester is used in conjunction with a laboratory scale pultruder to demonstrate a novel method of determining the fracture energy in shear. As pultrusions...

... The relations between the torsional loading applied at the foot and the axial rotations of the three leg joints (that is, ankle/boot, knee, hip) have been determined experimentally for three male test subjects of comparable height, age, and weight (1.83 m, 25 years, 90 kg). Experiments examined...

... In Part I of this two-part article, experiments that measured the response of the lower limb to dynamic, transient torsional loading applied at the boot/foot were described. Test variables included rotation direction, weight bearing, and joint flexion. For one of the three subjects tested, two...

Faults or other disturbances in an electrical distribution system can potentially feed back to the turbine-generator and produce large-amplitude torsional oscillations in the turbine-generator shaft. These transient torques, in combination with gravity-induced and misalignment-induced bending...

... The low-cycle fatigue (LCF) behavior of Waspaloy was studied in uniaxial and torsional loading for two heat treatments at 24 and 649°C. It was shown that for both heat treatments deformation and failure mechanisms were independent of stress state at 24°C. Deformation occurred by precipitate...
