Comparative study of smartphone screens using numerical analysis

Abstract

Abstract This work is focused on investigating smartphone screens using numerical analysis. Two smartphone screens are presented in this work for comparison. Apple and Samsung products will be analyzed, which are Sapphire and Gorilla Glass respectively. Extended finite element method and cohesive zone model for numerical analysis will be used. Software packages of Ansys, Code-aster and Salome Meca were used in this work for analysis to initiate and propagate crack in chosen structure. Brief introduction and literature review of the problem also presented in this work. To gather results for numerical analysis two different structure was build in software Ansys. Wedge shaped structure was built and analyzed to gather results of deformation. First analysis was done by using material properties of Gorilla Glass and second applying material properties of Sapphire. The results illustrated that Samsung product Gorilla Glass is more deformed if to be compared with Sapphire. Then a square shaped structure was created and was tested on fracture. Two different values were used to fracture the structure. The results showed that it is harder to fracture Sapphire than Gorilla Glass. Lastly crack propagation was analyzed. It was found that Gorilla Glass has less propagation than Sapphire.
