Burst Strength Analysis of Casing With Geometrical Imperfections
Journal of Pressure Vessel Technology, 2006 Accurately predicting the burst strength is very important in the casing design for the oil and gas industry. In this paper, finite element analysis is performed for an infinitely long thick walled casing with geometrical imperfections subjected to internal pressure.

Performance Investigation of Metaheuristic Niched-Pareto Genetic Algorithm for Imperfection Assessment of Structures [PDF]
Journal of Structural and Construction Engineering, 2019 Structures depending on the type of their application are subject to different types of loading, such as wind, earthquake and explosion loads. On the other hand, in order to increase the useful lifetime of the structures, optimal operating conditions ...

Reliability of silo structure with geometric imperfections [PDF]
PAMM, 2009 AbstractReliability of a silo structure with geometric imperfections is estimated. As the silo cylindrical constructions can be loaded with pressure below the atmospheric any geometric discrepancies are very dangerous and can significantly reduce their capacities. A probabilistic approach was applied. Two cases were considered.

Imperfect Geometric Control and Overdamping for The Damped Wave Equation [PDF]
Communications in Mathematical Physics, 2014 We consider the damped wave equation on a manifold with imperfect geometric control. We show the sub-exponential energy decay estimate in \cite{Chr-NC-erratum} is optimal in the case of one hyperbolic periodic geodesic. We show if the equation is overdamped, then the energy decays exponentially.
