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.
