Tooth Bending Strength of Hybrid Reinforced Plastics Gears(Machine Elements and Manufacturing)

Shear Strength of Lightly Reinforced T-Beams in Negative Bending

Nine restrained T-beams were tested in a study of the negative moment region shear strength of lightly reinforced concrete T-beams. Variables included the longitudinal reinforcement ratio p, (0.47 percent and 0. 70 percent) and the nominal stirrup strength (0 to 84 psi [0 to 0.60 MPa]). The test results are compared with the shear provisions of "Building Code Requirements for Reinforced Concret...

Bending strength simulation of asymmetric involute tooth gears

In order to enhance the load capacity of gears, researchers take notice in the asymmetric tooth gears. Asymmetric gear which has higher pressure angle of back tooth aiming to improve banding strength has been analyzed (Deng, et al., 2003). Brown et al. (Brown, et al., 2010) investigate the asymmetric tooth from both point of view of bending and scuffing. Kruger et al. (Kruger et al., 2013) anal...

Micromechanical voxel unit cell for strength analysis of fiber reinforced plastics

For the strength analysis of unidirectional laminae an unit cell approach is illustrated. The unit cell is modeled with an approximate voxel mesh instead of a conventional mesh. Strengths are determined with continuum damage mechanics. A fracture energy formulation is applied to alleviate mesh dependency in the softening behavior. For direct loads the unit cell shows good capabilities for the p...

Impact of High Strength Rebars on Seismic Behavior of Lightly Reinforced Boundary Elements

Considering economical reasons and attempting to reduce carbon foot print of concrete structures, there is increasing tendency toward use of high strength reinforcement in seismically active regions. ACI 318-19, Iranian steel rebars standard INSO 3132 and next edition of Iranian national building allow the use of high strength rebars in elements of ductile force resisting systems. Therefore it ...
