COMPARISON OF ERROR FOR DIFFERENT APPROXIMATION FUNCTIONS IN THE DUAL RECIPROCITY METHOD
|
| |
|
Summary :
|
|
SINCE THE PUBLICATION OF A BOOK ABOUT THE DUAL RECIPROCITY METHOD IN 1992 THERE HAS BEEN MUCH RESEARCH INTO THE DEVELOPMENT OF APPROXIMATION FUNCTIONS EMPLOYED WITH THE METHOD. MANY NEW FUNCTIONS HAVE BEEN PROPOSED AND USED TO SOLVE ENGINEERING PROBLEMS. GIVEN THIS WEALTH OF NEW FUNCTIONS, IT IS IMPORTANT TO BE ABLE TO SELECT AN ADEQUATE FUNCTION FOR A GIVEN PROBLEM, AND IN ORDER TO DO THIS IT IS NECESSARY TO KNOW SOMETHING ABOUT THE PROPERTIES AND BEHAVIOUR OF EACH. TO THIS END IN THIS PAPER SEVERAL EXAMPLES ARE SOLVED USING A WIDE RANGE OF FUNCTIONS AND THE RESULTS OBTAINED WITH EACH FUNCTION COMPARED WITH A VIEW TO ESTABLISHING TENTATIVE CRITERIA FOR CHOOSING THE FUNCTION.
KEY WORDS: DUAL RECIPROCITY; BOUNDARY ELEMENTS; APPROXIMATION FUNCTIONS;
COMPARATIVE ERROR. |
