COMPUTER EVALUATION OF AUTOMOBILE BARRIER SYSTEMS

COMPUTATIONAL PROCEDURES AND TWO COMPUTER PROGRAMS ARE PRESENTED FOR THE ANALYSIS OF AUTOMOBILES STRIKING DEFORMABLE PROTECTIVE BARRIERS. A LARGE DISPLACEMENT, INELASTIC, DYNAMIC STRUCTURAL ANALYSIS PROBLEM IS SOLVED. THE BARRIER IS IDEALIZED AS A PLANE FRAMEWORK MADE UP OF INELASTIC ONE-DIMENSIONAL ELEMENTS OF A VARIETY OF TYPES. THE AUTOMOBILE IS IDEALIZED AS A PLANE RIGID BODY SURROUNDED BY DISCRETE INELASTIC SPRINGS. THE STRUCTURAL ANALYSIS PROBLEM IS SOLVED BY A STEP BY STEP METHOD. USER'S GUIDES FOR TWO COMPUTER PROGRAMS, IDENTIFIED AS BARRIER IV AND BARRIER V, ARE INCLUDED. BARRIER V DIFFERS FROM BARRIER IV IN BEING APPLICABLE TO BARRIERS WITH MORE THAN ONE ITERACTION INTERFACE. RESULTS FOR A VARIETY OF EXAMPLES ARE PRESENTED, INCLUDING SOME IN WHICH EXPERIMENTAL AND COMPUTED RESULTS ARE COMPARED. THE AGREEMENT IS QUITE CLOSE IN VIEW OF THE COMPLEXITY OF THE PROBLEM. /FHWA/
