EXPERIMENTAL TECHNIQUES FOR ANALYSIS OF TRANSVERSE IMPACT ON BEAMS

PROCEDURES WERE DEVELOPED TO FACILITATE THE LABORATORY INVESTIGATION OF THE EFFECTS OF SHORT-DURATION TRANSVERSE IMPACT LOADING ON SIMPLY SUPPORTED BEAMS. THE PARTICULAR BEAM INVESTIGATED WAS ALUMINUM, WITH CONSTANT RECTANGULAR CROSS-SECTION. SIX LOADING CONDITIONS WERE EXAMINED, CONSISTING OF A CENTRAL IMPACT FROM THREE HEIGHTS FOR EACH OF TWO SPHERICAL MASSES. THEORETICAL ANALYSIS WAS MADE OF THE FREQUENCY AND DEFLECTION CHARACTERISTICS FOR TEN EQUALLY SPACED LOCATIONS ON THE BEAM, UNDER THE ASSUMPTION OF EULER'S BEAM THEORY. EXPERIMENTAL DATA WERE COMPARED WITH THEORETICAL VALUES TO GIVE AN INDICATION OF THE EFFECTIVENESS OF THE THEORETICAL SYSTEM IN REPRESENTING THE PHYSICAL SYSTEM. IT WAS CONCLUDED THAT THE THEORY GIVES A GOOD REPRESENTATION OF THE PHYSICAL SYSTEM, ESPECIALLY WITH RESPECT TO THE FREQUENCY CHARACTERISTICS. /RRL/
