근사적 가중함수를 이용한 보강된 균열평판의 응력강도계수 계산에 대한 연구
A study on the calculation of stress intensity factor for a patched crack using approximate weight function
초록
A cracked-plate with a patch bonded on one side is treated with a crack-bridging model: assuming continuous distribution of springs acting between crack surfaces. the approximate weight function was introduced to obtain the stress intensity factor of patched crack subjected to residual stress or non-uniform stress. The stress intensity factors for the partially patched crack within finite plate or the patched crack initiated from a notch were successfully obtained by numerical calculation.
