Torsional stiffness of reinforced concrete members subjected to pure torsion

open access: yesMagazine of Concrete Research, 1972
Synopsis A method is described for determining the torsional stiffness at the cracked stage of reinforced concrete members subjected to a pure torsional moment. The method is based upon a truss analogy for torsion. Theoretical expressions are deduced for the Torsional stiffness of beams of arbitrary and rectangular cross-sections.

Effect of Gradient Microstructure Induced by Pre-Torsion on Hydrogen Embrittlement of Pure Iron

open access: yesCorrosion Science, 2021
Building a gradient structure can achieve overall improvement of multiple properties of metal materials. However, the investigation on hydrogen embrittlement (HE) behavior of gradient structure alloys has not been reported so far. This study investigated

Microhardness and Microstructural Evolution in Pure Nickel During High-Pressure Torsion

open access: yesScripta Materialia, 2001
The microhardness and microstructural evolution during high pressure torsion testing in samples of pure nickel were investigated. Results were obtained on Ni samples subjected to annealing prior to high pressure torsion.

Pure torsion of prestressed flanged sections

Building and Environment, 1979
Abstract The paper reports on an experimental investigation of 14 pretensioned prestressed T beams in pure torsion and proposes an equation, based on statistical analysis, for predicting cracking torques in plain, reinforced and prestressed concrete flanged sections.

On Pure Torsion of a Cantilevered Open Section

Transactions of the Canadian Society for Mechanical Engineering, 1975
Non-uniform torsion of an elastic torsion bar leads invariably to nonlinear normal stresses in addition to those obtained without consideration of changes of geometry due to deformation. The nonlinearity of the resultant stress system has an effect upon the location of the twist centre and thus on the applicability of Maxwell’s reciprocity theorem ...

Splitting torsion pairs over pure semisimple rings

Journal of Pure and Applied Algebra, 2015
Let \(R\) be a left pure semisimple ring and \((\mathcal{D,C})\) a splitting torsion pair of the family \(R\)-ind of indecomposable left \(R\)-modules, i.e., a partition of \(R\)-ind such that \(\Hom_R(D,C)=0\) whenever \(D\in\mathcal D\) and \(C\in\mathcal C\).
