VIV analysis of pipelines under complex span conditions
boundary condition (BC) fatigue limit state (FLS) force model (FM) kilometer post (KP) mode shape natural frequency response model (RM) vortex-induced vibration (VIV) ultimate limit state (ULS) unit stress
2011/9/13
Spans occur when a pipeline is laid on a rough undulating seabed or when upheaval buckling occurs due to constrained thermal expansion. This not only results in static and dynamic loads on the flowlin...
Life-span of clautions to ssical solhyperbolic geometric flow in two space variables with slow decay initial data
hyperbolic geometric °ow Riemann surface Cauchy problem classical solution life-span
2018/4/20
In this paper we investigate the life-span of classical solutions to the hyperbolic geometric °ow in two space variables with slow decay initial data. By establishing some new estimates on the solutio...
