Abstract

Ovim radom obrađena je tema posuda tankih stijenki. Objašnjena je općenita uporaba tankostjenih posuda i što ih uopće definira. Za razumijevanje naprezanja koja se u njima javljaju pojašnjena je Laplaceova osnovna jednadžba za određivanje naprezanja. Na temelju prikazanih primjera dobivena su različita naprezanja koja se javljaju u stijenkama posuda s obzirom na njihov oblik i nametnuto unutarnje opterećenje. Detaljnije su pojašnjeni cilindrični oblici posuda i tankostjeni kružni prstenovi. Navedena je i veza naprezanja i deformacija te kako ju možemo dobiti iz vrijednosti naprezanja. Znanje o tankostjenim posudama prezentirano je na dva primjera.

Abstract (english)

This paper deals with the topic of thin-walled vessels. The general use of thin-walled vessels and what defines them in general are explained. To understand the stresses that occur in them, Laplace's basic equation for determining stresses is explained. Based on the presented examples, different stresses occurring in the vessel walls with respect to their shape and the imposed internal load were obtained. The cylindrical shapes of the vessels and the thin-walled circular rings are explained in more detail. The relationship between stress and strain and how we can get it from the stress value is also stated. Knowledge of thin-walled vessels is presented on two examples.
