수치해석을 도입한 파괴역학의 기하학적 고찰과 응력확대계수의 합성에 관한 연구 = The Geometric Consideration of Fracture Mechanics in a Numerical Analysis including Research in the Composition of Stress Intensity Factor

다국어 초록 (Multilingual Abstract)

Stress intensity factor is one of the most important factors in analysing fracture mechanics. To access fracture mechanics easily, the geometric consideration of fracture mechanics, particularly in stress intensity factor calculation, is studied. When geometric consideration of crack tip opening for the stress intensity factor ?? of opening mode case and for the stress intensity factor ?? of sliding mode case is successfully set up, the combined mode stress intensity factor ?? can be interpreted from the geometrically introduced ?? and ??.
As the ??, ?? and ?? can be calculated from the physical displacement calculation in the consideration of the crack opening geometry, we can obtain each stress intensity factor by adopting displacement or stress value from the numerical analysis calculation for the various configurations of the geometry we need to analyse.
