Abstract

This paper deals with a time-domain boundary element technique suitable for the analysis of linear viscoelastic materials in the presence of transient temperature field. Thermorheologically simple behavior has been assumed. Following an exposition of the boundary element formulation, the numerical results of example problem have been presented.

이 논문은, 선형점탄성체가 과도온도상태에 있을때의 거동을 시간영역 경계요소법에 의해 해석하고 있다. 점탄성체에 대해서 '열유동단순'거동을 가정하였다. 경계요소 공식화과정을 설명한 후, 예제문제에 대한 수치해석 결과를 보여주었다.
