Abstract
THE OBJECTIVE OF THE PROPOSED RESEARCH IS TO DEVELOP A METHOD FOR MEASURING RESIDUAL STRESS GRADIENTS IN THE WALL OF ARTILLERY SHELLS, BASED ON A NOVEL ACOUSTO-ELASTIC APPROACH, USING A BROADBAND ULTRASONIC SIGNAL AND SURFACE-HUGGING GUIDED WAVE MODES. THE RESEARCH WILL INCLUDE THE DEVELOPMENT OF SUITABLE TOOLS AND SOFTWARE FOR DATA ANALYSIS. IT IS ALSO PROPOSED HERE TO DEVELOP AN ULTRASONIC STRESS-ROSETTE TO EVALUATE PRINCIPAL STRESS DIRECTION. AS A RESULT OF THE PROPOSED RESEARCH, IT IS HOPED THAT A NEW METHOD WILL BE DEMONSTRATED, CAPABLE OF SOLVING MANY RESIDUAL-STRESS ANALYSIS PROBLEMS. SUCH A TOOL SHOULD FIND AN EXTENSIVE APPLICAATION BOTH IN GOVERNMENT AND INDUSTRIAL LABORATORIES.
