Abstract

An object oriented programming(OOP) framework is presented to solve plane elastostatic contact problems by means of the boundary element method(BEM). Unified modeling language(UML) is chosen to describe the structure of the program without loss of generality, even though all implemented codes are written with C++. The implementation is based on computational abstractions of both mathematical and physical concepts associated with contact mechanics involving geometrical nonlinearities and the corner node problems for multi-valued traction. The overall class organization for contact analysis is discussed in detail. Numerical examples are also presented to verify the accuracy of the developed BEM program.

본 논문에서는 경계요소법으로 평면 탄성 접촉문제를 해석하기 위하여 객체지향기법을 이용하여 프로그램을 구성하였다. 개발된 프로그램의 상세는 UML을 통하여 기술함으로써, C++로 구현된 프로그램이 일반적인 객체지향기법을 통해 구현될수 있도록 하였다. 개발된 프로그램은 접촉해석의 비선형성과 모퉁이 문제를 포괄할 수 있도록 추상화된 객체로 구현되었다. 접촉해석에 관련된 객체의 상세를 기술하였으며, 수치해석 예제를 통하여 개발된 프로그램의 정확성을 검증하였다.
