Nonlinear Buckling Finite Element Analysis to Estimate Collapse Pressure of Thick Cylinder under Hydrostatic Pressure [PDF]
한국해양공학회지, 2019 In order to perform a pressure chamber experiment with a circular cylindrical pressure vessel, the dimensions of the cylinder need to be determined in the range of the maximum externally applied pressure of the chamber to create the collapse process.

Breaking the Rayleigh-Plateau instability limit using thermocavitation within a droplet [PDF]
, 2013 We report on the generation of liquid columns that extend far beyond the traditional Rayleigh-Plateau instability onset. The columns are driven by the acoustic pressure wave emitted after bubble collapse.

Buckling Analysis of Corroded Pipelines under Combined Axial Force and External Pressure
Metals, 2022 Affected by a complex environment, corrosion is a common defect in steel pipelines. Moreover, steel pipelines are subjected to large axial forces during their installation and operation. Corroded deep-sea steel pipelines are prone to local buckling under

Wellbore stability analysis of layered shale based on the modified Mogi–Coulomb criterion
Petroleum, 2020 Borehole instability was frequently encountered during shale gas drilling. Most conventional models are not applicable to layered formation's wellbore stability analysis on account of anisotropic strength characteristic.

Negative Pressure and Naked Singularities in Spherical Gravitational Collapse [PDF]
, 1996 Assuming the weak energy condition, we study the nature of the non-central shell-focussing singularity which can form in the gravitational collapse of a spherical compact object in classical general relativity.

A numerical model for cloud cavitation based on bubble cluster
Theoretical and Applied Mechanics Letters, 2017 The cavitation cloud of different internal structures results in different collapse pressures owing to the interaction among bubbles. The internal structure of cloud cavitation is required to accurately predict collapse pressure.
