Abstract

Delo predstavlja numerični model večnamenske deske z eksperimentalno dobljenimi materialnimi lastnostmi. S pravilnim numeričnim modelom lahko napovemo togostne in trdnostne lastnosti deske pred samo izdelavo prototipa. S tem je lahko naš prototip boljši od konkurence, saj je virtualno testiranje in optimiziranje hitrejše od eksperimentalnega. V delu je predstavljen popis elastičnega obnašanja laminata ter porušitvene hipoteze za posamezno kompozitno plast. S pomočjo MKE smo deski povečali togostne in trdnostne lastnosti. Z numerično optimizacijo deske smo dosegli, da deska prenese dane kritične obremenitve.

Secondary title: Mechanical analysis of a composite stand up paddle board
Secondary abstract: This thesis presents a numerical model of a multipurpose board with experimentally obtained material properties. By using the proper numerical model, it is possible to predict the properties of stiffness and strength of the board before the production of the prototype itself. Since virtual testing and optimization are faster than their experimental versions, this can enhance our prototype's quality when compared to our competition. The thesis also presents a survey of elastic behaviour of laminate and failure hypothesis of each individual composite layer. By using FEM we increased the stiffness and strength of the board. Numerical optimization enabled the board to withstand given critical loads.
