Abstract

U ovome radu analitički i numerički analizirano je savijanje kompozitne ploče uslijed koncentrirane sile u smjeru normale na ravninu ploče. Analitičkom metodom izvedena je jednadžba progiba koja je programirana u Matlab-u. Numerička analiza provedena je u programskom paketu Abaqus metodom konačnih elemenata na više načina. Uspoređeni su rezultati numeričke i analitičke analize za različite rasporede slojeva kompozitnog elementa i za različita hvatišta sile. Analizirana su naprezanja koja se javljaju u kompozitnim pločama te razni faktori koji bi mogli utjecati na naprezanja ili na progib.

Abstract (english)

In this Bachelor thesis, the bending of a composite plate due to a concentrated force normal to the plane of the plate was analyzed analytically and numerically. An analytical method was used to derive the deflection equation in a programming language and executed in the Matlab program. Numerical analysis was carried out using the finite element method in the Abaqus software package using various modeling techniques. The results of numerical and analytical analyses were compared for different layups of the layers of the composite element and for different force application locations. The stresses that occur in composite plates were analyzed, as well as various factors that could influence the stresses or the deflection.
