Andreas Almqvist's research belongs to the field of Tribology. The research is theoretically biased and deals with modelling and simulation of tribological contacts. The focus is on the influence of surface roughness on film formation, friction and wear. The effects that arise in these type of contacts has been paid special interest, e.g., real area of contact in an unlubricated contact , the load carrying capacity and powerloss in a hydrodynamically lubricated contact, etc.
