AIM:- To study the Impact Testing m/c and Perform charpy impact test.
APPARATUS :- Impact testing m/c, charpy test specimens of mild steel, Aluminium, Vernier caliper, specimen setting fixture.
THEORY :- In manufacturing locomotive wheels, coins, connecting rods etc. the components are subjected to impact (shock) loads. These loads are applied suddenly. The stress induced in these components are many times more than the stress produced by gradual loading. Therefore, impact tests are performed to asses shock absorbing capacity of materials subjected to suddenly applied loads. These capabilities are expressed as (i) Rupture energy (ii) Modulus of rupture and (iii) Notch impact strength.
