Effect of Helical Buckling on Wellhead Height Growth of High Temperature Gas Well under Deepwater Condition

Shiyou jixie, 2019
Wellhead growth has a significant impact on the safe production of deepwater high temperature oil and gas wells. The traditional prediction model only take into account of the effect of temperature effect and expansion effect on wellhead growth but ...

Supercapacitor Safety: Overcharge‐Induced Failure Mechanisms in Electrochemical Double‐Layer Capacitors

Advanced Science, EarlyView.
Time‐resolved synchrotron radiography reveals the internal evolution of electrochemical double‐layer capacitors under abusive overcharge. EDLCs are shown to follow a thermally driven failure pathway involving electrolyte decomposition, gas generation, and structural collapse, distinct from chemically driven thermal runaway effects of Lithium‐ion ...

Two-Dimensional Discrete Model for Buckling of Helical Springs

Procedia Structural Integrity, 2019
Abstract The classical theory of helical spring instability is based on the buckling of an equivalent column. Alternatively, more advanced methods are found in literature, involving the numerical solution of the displacement field of the helical wire.
