Quality of the castings is affected by several factors which the designer should take into consideration during the product development process. Although residual stress is one of those, it is often not considered in practical computations.Hence residual stresses are one of the forgotten areas in designing of machine parts. This paper is focused on the investigation of residual stresses in a high pressure die casted component, with the aim of extending its service life. The investigation was done on a variety of specimens, cast aluminum flywheel. In evaluating the residual stresses in the part, two tools-simulation and physical measurement were used. Moreover, comparison with these two methods is also done at an area of interest on the flywheel. The simulation was carried out by using MAGMAhpdc-a module for high pressure die casting process, from the software MAGMAsoft; while for the physical measurements, the hole drilling method was used. The findings obtained from this study...
