Stress wave propagation in adhesively bonded similar and dissimilar circular cylinders

摘要

This study addresses the wave propagation in adhesively bonded similar and dissimilar circular cylinders under an axial impulsive load. The four configurations are considered such as adhesively bonded aluminum-aluminum (Al-Al), steel-steel (St-St), aluminum-steel (Al-St), and steel-aluminum (St-Al) joints. The governing equations of the wave propagation are partial differential equations which are not usually amenable for analytical solutions under complex boundary conditions. Therefore, they are solved numerically using the finite difference method for spatial and temporal discretization. Each component of the adhesively bonded circular cylinders exhibits completely different stress and deformation states under an axial impulsive load. The axial displacement
