A Photoelastic Study on Change of Stress Concentration Factor Due to Unsymmetrical Change of Notch Angle
Pure Bending Moment 하(下)에 있는 Notched Strip에서의 Notch Angle의 비대칭적(非對稱的) 변화(變化)에 의(依)한 응력집중계수(應力集中係數)의 변화(變化)
Abstract
It is investigated that in what shape the stress concentration factor of a notched strip under pure bending changes due to unsymmetrically varying notch angle. Four models made of CR-39, having parameters of r/d-0.225, h/r=4; r/d=0.225, h/r=2; r/d=0.4, h/r=4 and r/d=0.4, h/r=2 respectively as shown in Fig.1, Fig.2 and Table are tested with the use of polariscope. For each model, notch angle is unsymmetrically varied from
