To perform bending fatigue tests on fiber materials, a specially designed bending fatigue test apparatus has been developed.
The paper presents two test rigs designed at the University of Pisa to perform bending fatigue tests on full scale drill pipe connections used for oil drilling.
A custom-designed sheet strip tribo-tester that includes bending deformation was used to perform tribological tests on tool steels having surface treatments.
The aim of this chapter is to show how to derive macroscopic strength properties in terms of generalized stresses such as membrane forces and bending moments in order to perform the yield design at the structure level.
Nevertheless, it can be clearly seen from the time series related the burying, as well as from the NMR-images, that the forward-movement of a limb occurs during bending of the body to the contralateral side, while the backward movement is performed during bending to the ipsilateral (collateral) side (see Figure 6).
Another exercise involved sitting with legs extended straight and then performing side bends to rest the arms on the mat behind the body, alternatingly on the left and right side.
He and other prisoners, caught praying together, were blindfolded, handcuffed and forced to perform knee bends for hours in time to a whistle, or be whipped.
His strength, for a 51-year-old, was astonishing — at one point, he dropped to the floor and held a plank position, bent his elbows as if to perform a push-up, then hopped across the floor several times without breaking form.
The (x′,y′,z′) can then be taken as the coordinate at next time step to perform the bending dynamic simulation.
The semi-circular bending specimen (SCB) is employed to perform a total number of 36 mixed mode fracture tests on the prepared nanocomposites.
