Vibration of pipelines under flexural dynamic loads
A SYSTEM OF eight-coupled first-order partial differential equations describing the vibration response of pipelines under external flexural loads is derived. The decoupling of these equations yields a system of eight fourth-order partial differential equations. An analytical solution is achieved with the aid of integral transforms. Vibration analysis of pipelines subjected to impact and harmonic loads is provided.
