The appearance of these equations promoted the development of Boussinesq-type equations. In shallow water, the depth of water has significant effects on the propagation...

For thick pipelines, the deformations are dominated by the bending caused by the seismic fault and the main failure pattern is a dent of the compression side on the bends which even develop into a self-contact collision of the inner wall. For thin pipelines...

... buckling can occur through lateral or upheaval buckling modes, however, these two buckling modes are not essentially failure modes (Karampour et al., 2013). Propagation buckling is the most critical one that increases the chance of pipeline failure, especially in the ultra-deep waters (Albermani et al...

However, the SSC propagation behavior is not clear yet when hard–zone with high hardness over 250 HV0.1 is present at the surface. In this paper, the effect of hardzone depth and H2S partial pressure...
