Özet:

 

The effect of the pre-stress and internal Pa6 (cast-polyamide) material
on the bending behavior of the aluminum tube is investigated experimentally. Finite
element studies have been carried out to better understand the effect of
pre-stress on the cross-section of tube and to shed light on the experimental
studies. From the simulation studies, it was concluded that the effect of the
pre-stress on the load carrying capacity of the tube is limited. After finite
element studies, experimental studies were performed. In experimental studies,
the lower cross-section of the tube was subjected to 175 MPa stress
corresponding to 93% of the yield strength of the material. The tensile stress
in the tube during the loading is reduced by applying pressure to the lower
cross section of the tube beam. In addition, a change in the load carrying
capacity of the tube was investigated using a Pa6 ring to delay local buckling.
As a result of the experiments, it was found that the pre-stress significantly
improved the bending behavior of the tube in the elastic region, while reducing
buckling displacement.  Application of both
pre-stress and internally reinforcement enhanced bending performance of the
tube in both elastic and plastic regions. Load carrying capacity of pre-stressed
and internally reinforced tube was increased 1.67 times
according to the base tube.  .
