Vibration isolators are used in launch vehicles to protect sensitive electronic equipments from the rigors of flight structural vibrations during the lift-off and ascent phase. Failure of one such vibration isolator made of AISI 304 is reported in the present study after ground level testing has been completed.  Finally, it was concluded that micro cracks formed during the deep drawing operation due to large strains at the fore end corner propagated during vibration testing resulting in the failure of the body of the vibration isolator.
