چکیده

Abstract. Thin-walled mechanical components, such as beams, plates and shells, are widely used structural components in several engineering fields, particular mechanical, aeronautical aerospace sectors. The purpose of this work is to analyse the cross-ply bending behaviour cylindrical spherical shell structures using finite element method. Hence, numerical models, realized commercial software, were solid approaches compared with analytical methods appreciate their advantages. In research, a Navier solution close form for high-order theories, developed Carrera Unified Formulation (CUF) approach, has been reported, where elastic model variational principle virtual three-dimensional linear theory equations results obtained Mathematica software. furnished by method elasticity solutions given literature Navier’s benchmark comparing terms maximum displacement stress distribution along principal structure direction. However, cannot provide sufficient data describe tensional deformational state at all points especially laminate thickness. Wishing obtain complete description plate's behaviour, it necessary use approach associated increase calculation time. contrast, based on CUF shows very efficient composite its should be preferred classical lamination if an accurate necessary.

Numerical investigation of the parameters of a prismatic lithium ion battery under load for electrical vehicle

Electric vehicles and hybrid electric vehicles are a suitable alternative for vehicles with hydrocarbons fuels to reduce pollution and fossil resources. The batteries operate as the driving force for these vehicles. One of the most critical parameters of the battery is computing the state of charge (SOC). The best range for SOC of lithium-ion battery is between 20% and 90%, and charging and dis...
