3D character of backward erosion piping [PDF]
, 2017 Backward erosion piping is an important failure mechanism for cohesive water-retaining structures which are founded on a sandy aquifer. Nowadays, piping research and safety assessments are often based on experimental or numerical modelling using ...

Occurrence of plastic collapse under ratcheting due to gravity and seismic loading
Mechanical Engineering Journal, 2022 The most dominant failure mode of piping components under seismic loading is fatigue failure with ratcheting. While it was confirmed via the experimental tests in the past, the Primary stress limit is applied to seismic loading to prevent plastic ...
