Mikro-mekanisk modellering av metallpulver (Swedish)
We study the problem of packing spheres of different radii into a rigid container. The spheres are packed as densely as possible so they neither overlap nor cross the boundaries of the container. The packed spheres are then meshed in preparation for finite element analysis. The spheres are meshed individually (separately) without taking care of the contact surface between spheres or containers wall. The last step is the hydrostatic pressing of the spheres made of elastic-plastic materials and with simplified contact conditions. Such simulations are of interest to the metallurgist because they can show differences in structure between grain surfaces and centres.
