본 연구에서는 복합재료의 접착이음에 대한 강도 평가법을 확립하기 위한 기 초연구로써 접착이음의 가장기본적인 형태의 하나인 겹치기 이음(single-lap joint: SLJ)에 대한 응력해석과 정적 및 피로 강도시험을 실시하고, 종래의 강도평가법의 문 제점을 파악.검토하고 정량적이고 통일적인 접착이음의 강도평가법의 확립 및 설계 기 준의 설정에 대한 새로운 방향을 모색 하고저 한다.

An analytical model for the lateral vibration of beams with a bonded lap joint and partial layered dampers has been proposed in this paper. Both shear and normal forces acting along the interface between the elastic and viscoelastic layers were considered in the vibration analysis. Analytical results were compared with those obtained by a finite element method. Effects of the size and location of layers in partial dampers on system loss factor($\eta_s$) and resonant frequency($\omega_r$) were studied. which showed that partial dampers adhered to the site exhibiting the maximum amplitude of vibration were most influential in the increase of $\eta_s$ and the decrease of $\omega_r$. Specific system loss factor( $\eta_s$ divided by total mass of system) was also evaluated in the analysis.
