Abstract
Završni rad bavi se problemom torzije – slučajem opterećenja koji uzrokuje uvijanje štapova i greda. Nakon upoznavanja osnovnih pojmova i načina na koji torzija djeluje na elemente, definirat će se torzija na kružnom poprečnom presjeku te ustanoviti zakon raspodjele posmičnih naprezanja pri čemu se uvode pojmovi modula posmika, (relativnog) kuta torzije, (polarnog) momenta tromosti i torzijske krutosti – ključnih pojmova potrebnih za razumijevanje torzije kao opterećenja. Nakon definicije osnovne teoretske podloge, uvode se kompleksniji problemi – statički neodređeni zadaci pri torziji i dva načina rješavanja istih – metoda presjeka i metoda uvjeta deformacije koja ovisi o načinima pričvršćenja elementa za podlogu. Nadalje, vrhunac završnog rada predstavlja Prandtlova membranska analogija – inženjersko rješenje temeljeno na diferencijalnim jednadžbama kojima se rješava problem torzije na štapovima proizvoljnog poprečnog presjeka iz kojih su izvedeni izrazi za posmična naprezanja tankostjenih otvorenih i zatvorenih profila koji se detaljnije obrađuju numeričkim primjerom koji naposljetku završnog rada obuhvaća prethodnu teoretsku podlogu i objedinjuje istu u cjelinu.
Abstract (english)
This thesis deals with the problem of torsion - a case of loading that causes the rods and beams to twist. After learning the basic concepts and how the torsion acts on the elements, the torsion will be defined on a circular cross section and the law of distribution of the shear stresses will be established, introducing the terms of the shear modulus, (relative) torsion angle, (polar) moment of inertia and torsional rigidity - key concepts needed to understand torsion as a load. After defining the basic theoretical substrate, more complex problems are introduced - statically indefinite torsion problems and two ways of solving them - the intersection method and method of deformation conditions, which depend on the way of fixing the element to the substrate. Furthermore, the focus of the thesis is the Prandtl Membrane Analogy - an engineering solution based on differential equations that solves the problem of torsion on rods of arbitrary cross-section from which expressions are made for shear stresses of thin-walled opened and closed profiles, which are dealt with in more detail by a numerical example that covers the thesis’ previous theoretical background and integrates the same into an unit.
