Analysis and prediction of welding distortion in complex structures using elastic finite element method
The Elastic Finite Element Method based on the inherent strain theory is used to predict the welding distortion of ship structures. In addition, a method to predict welding distortion of complex structures by using elastic ...
Shell curvature as an initial deformation: A geometrically exact finite element approach
(JOHN WILEY & SONS LTD, 2009)
An alternative approach for the analysis of arbitrarily curved shells is developed in this paper based on the idea of initial deformations. By `alternative` we mean that neither differential geometry nor the concept of ...
Complex modal analysis of a vertical rotor through finite element method
Natural frequencies were analyzed (axial, torsional and flexural) and frequency response of a vertical rotor with a hard disk at the edge through the classical and complex modal analysis. The mathematical modeling was based ...
Delimitation of safety zones by finite element analysis
(Taylor & Francis, 2008)
This paper deals with the determination of safety zones and local minima by using finite element analysis. Used is made of finite element method in order not to constraint the analysis by neither the assumptions in the ...
