Abstract :
Deflection usually refers to the deformed shape
and position of a member subjected to bending loads. More
specifically, however, deflection is used in reference to the
deformed shape and position of the longitudinal axis of a
beam. In deformed condition, the neutral axis, which is,
initially a straight longitudinal line assumes some
particular shape, which is called deflection curve. A
laboratory Investigation of the load deflection
characteristic of selected materials (Steel, Aluminium and
Brass) had been done. The Experimental programme
involves the testing beam for deflection with structures test
frame. Tests show that the recorded maximum deflection
for Steel is 1.61 mm (downward), while for Aluminium and
Brass beams deflection are 4.23 mm (downward) and 3.10
mm (downward) respectively. The load-deflection
behaviors of the beams are essentially linear within the
elastic range of loading. Based on the findings of this
investigation, it was observed that the deflection behavior
of different materials is similar; however, the Aluminium
showed maximum deflection than the others beams.
