Reshaping process is a widely used method for producing tubes with non-circular cross sections. Owing to the friction between pipe and rolls, initial round pipe moves forward and consequently, it gradually formed into square or rectangular one. In practice, geometric profile of the rolls will be changed after a while. These changes would be detrimental the production of faultless products. Ther...

Many of the carbon and natural fibres used in composite reinforcement have a non-circular cross section. Recently non-circular, or flat, section glass fibre products become commercially available. This paper explores potential effects that such shapes may on micromechanics stress transfer at fibre–matrix interface resulting changes strength performance. Analytical modelling is to show how criti...

Mercier‘s localized perturbed criterion of stability near an arbitrary modulated curvature magnetic axis of a non-circular toroidal plasma cross section is investigated. In this magnetic configuration, the magnetic surfaces arbitrarily rotate around the magnetic axis. The influence of the non-circular cross section of the magnetic surface and that of the modulation of the magnetic axis on the d...

an elliptical tank cross-section is formulated to explore and optimization method, based on a real-coded genetic algorithm to enhance the roll stability limit of a tank vehicle. a shape genetic algorithm optimization problem is applied to minimize the overturning moment imposed on the vehicle due to c.g. height of the liquid load, and lateral acceleration and cargo load shift . the minimization...
