Določevanje nosilnosti lepljenega spoja zaskoka in dekorativne površine

Matoša, Gašper (author), Klemenc, Jernej (mentor)

Raziskava se osredotoča na opredelitev metode določanja nosilnosti lepljenih spojev v zgodnjih fazah razvoja izdelkov, kjer so razpoložljivi podatki običajno omejeni, kar zmanjšuje natančnost napovedi nosilnosti. Iskanje rešitve je vključevalo zasnovo preizkuševališča, izdelavo vzorcev in izvedbo meritev pod različnimi pogoji. Izvedli smo tudi posebne računalniške simulacije istega spoja, s katerimi smo primerjali rezultate eksperimentov. Uporabljeni korekcijski faktorji, ki povezujejo nosilnost, določeno s pomočjo računalniških analiz, z nosilnostjo iz meritev, so bili pridobljeni z natančno izbrano metodologijo. Ta omogoča hiter in celovit vpogled v ustreznost uporabljenega lepila in geometrije spoja v različnih pogojih. Ugotovili smo, da izpeljani korekcijski faktorji omogočajo napoved napetosti v zgodnjih fazah razvoja, kar prispeva k razvoju zanesljivejših in trajnejših izdelkov. Za napoved deformacij spoja je potrebno razviti drugačno metodo.

• Title: Determining the load capacity of a clip glued to a decorative surface

Abstract

The research focuses on defining the method for determining the load-bearing capacity of bonded joints in the early stages of product development, where available data is usually limited, reducing the accuracy of load-bearing predictions. The search for a solution involved the design of a testing facility, the fabrication of samples, and the execution of measurements under various conditions. We also conducted specialized computer simulations of the same joint to compare the experimental results. The correction factors used, which link the load-bearing capacity determined through computational analysis with that obtained from measurements, were derived using a carefully selected methodology. This approach provides a quick and comprehensive insight into the suitability of the adhesive and joint geometry under different conditions. We found that the derived correction factors allow for stress prediction in the early stages of development, contributing to the creation of more reliable and durable products. A different method is needed to predict joint deformation.
