Abstract In this paper, we conduct research of the waveguide strength under icing. Icing is assumed to be uniform along perimeter and length waveguide, so ice deposits considered in form an equivalent increase density structure. As a result, icing problem reduced gravitational bending waveguide. Waveguide has thin-walled rectangular cross-section; therefore, solution demand using theory plate. ...

The aim of the research - to investigate behavior thin-walled beam I-section loaded with bending and torsion using theoretical, numerical, experimental approaches. In this paper, main criteria for consideration different methods analysis is geometric characteristic section. results obtained by finite element method, numerical as well data are compared. method considering an additional degree fr...

Impact is one of very important subjects which always have been considered in mechanical science. Nature of impact is such that which makes its control a hard task. Therefore it is required to present the transfer of impact to other vulnerable part of a structure, when it is necessary, one of the best method of absorbing energy of impact, is by using Thin-walled tubes these tubes collapses unde...
