This bachelor thesis in mechanical engineering was performed during the spring2015 in collaboration with Composite Consulting Group in Laholm. TheComposites Consulting Group works mainly with design and details of differentcomposite projects, their main area is FE-calculations, 3D-modelling andmechanical tests with composite materials.The aim of this bachelor thesis was to simplify the calculation process of solidmechanics for sandwich panels by simulation with computer software. The goalwas to decrease the time for the design and calculation process of the constructionand the cost of the practical tests. Our task was to build a static three dimensionalmodel with the computer software Abaqus, where the result should correspondwith the practical pressure tests in laboratory.The project started with collection of material data from Composites ConsultingGroup and by learning the software Abaqus, simultaneously a specification wasdeveloped in corporation with the company. Later on, a static wheel pressuremodel in the software Abaqus was produced which simulated the behavior of thesandwich panel during static wheel-pressure by a pallet truck. The results from thewheel-pressure model were verified with the practical tests.The project led to a static three dimensional wheel- contact model with thesoftware Abaqus to calculate complex wheel-contact problems on sandwichpanels. The wheel-contact model corresponded to the practical test results. Thecontact model with Abaqus enabled faster and more efficient design anddevelopment process of new sandwich panels. It also provided better analysis ofthe sandwich panels’ behavior during wheel- contact loading.
