Abstract [sv]

Detta examensarbete beskriver undersökningen av kärnmaterial i en sandwichpanel under belastning. Arbetet har utförts tillsammans med CCG i Laholm, Sverige. Kärnmaterialen lämpar sig vid design av sandwichpaneler på grund av sin låga vikt och sin förmåga att klara av högt tryck. Då materialet uppvisar ett ickelinjärt beteende skapar det problem vid design av sandwichpaneler och leder till att materialsammansättningarna tillverkas konservativa mot verkligheten. Projektet har gått ut på reducera designprocessen genom att bygga upp och simulera materialmodeller i programvaran ABAQUS för att kunna analysera och förutse materialets beteende. Resultaten har presenterats i kraft- och förskjutningsdiagram samt visualiseringar och har försvarats med hjälp av teorier för kontaktmekanik samt matematik. Projektet har utförts på ett vetenskapligt sätt där hypotes verifieras mot teori för att sedan verifieras i experiment, allt för att säkerställa resultatet.

Abstract [en]

This thesis describes a study of the core materials used in composite panels under static indentation. The work was conducted together with CCG in Laholm, Sweden. These materials work well when designing sandwich panels due to their low weight and high compression strength. As the cores show a non-linear behavior problems can arise when constructing panels and oftentimes lead to choosing very conservative solutions that are not optimized.The main focus of this thesis has been the modelling and simulation of materials in the software ABAQUS to analyze and predict the materials behavior and reduce the time needed for the design of new panels. The result is presented in force- displacement plots as well as von Mises visualization plots and is sustained by theories of both contact mechanics and mathematics. The group endeavored to work in a scientific manner by verifying the hypotheses through theory and experiments in order to accomplish accurate results.
