    Abstract

    This project report deals with design aspects of the13; servohvdraulic loadframe and accessories installed at NAL for testing of aircraft materials. The design of hardware for mechanical testing is also carried out. The load frame is a dual column, fixed cross heads with xB1;5 ton actuator. The load cell is of integral design with xB1;5 ton load rating .This report includes details on fatigue testing machine load frame and load cell starting from the stuy of the to load pattern, designing, material selection, blueprints and fabrication. Also covered are C(T) type specimen testing including design of clevisgrips for mounting the specimen and COD gage for measuring the crack opening displacement. Calibration of load cell and COD gages is also taken up. The specimen holding grips developed for a component rig is described at the and13; Necessary mounting grips and adapter screws are designed and fabricated.
