Finite Element Analysis of Buckling of Thin Cylindrical Shell Subjected to Uniform External Pressure

One of the common failure modes of thin cylindrical shell subjected external pressure is buckling. The buckling pressure of these shell structures are dominantly affected by the geometrical imperfections present in the cylindrical shell which are very difficult to alleviate during manufacturing process. In this work, only three types of geometrical imperfection patterns are considered namely (a...

Finite Element Analysis Method for Detection of the Corona Discharge Inception Voltage in a Wire-Cylinder Arrangement

The inception voltage of the positive corona discharges (CIV) in a typical wire-cylinder electrode arrangement in air, under high voltage dc application, has been studied by implementing the Finite Element Analysis (FEA). Numerical analysis has been carried out on the electric field intensity, along the wire-cylinder gap axis, in order to determine the inception voltage of each air gap and defi...

An Efficient Strain Based Cylindrical Shell Finite Element

The need for compatibility between degrees of freedom of various elements is a major problem encountered in practice during the modeling of complex structures; the problem is generally solved by an additional rotational degree of freedom [1-3]. This present paper investigates possible improvements to the performances of strain based cylindrical shell finite element [4] by introducing an additio...

Finite Element Modeling of Compressor Discharge Tubes

Discharge tubes in hermetically sealed refrigeration compressors are often a source of fatigue failure which is not serviceable and necessitates the replacement of the compressor. The finite element method can be used to model the discharge tube to help prevent such failures and to reduce costs by optimizing the tube. This investigation considers techniques for modeling discharge tubes with fin...
