Investigation into Wrinkling of Aluminum Sheets in Deep Drawing Process Mohammad Reza Foudeh mohammad mr59@yahoo com 2009 07 04 Department of Mechanical Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language FarsiSupervisor Dr Naser Nehzat n nehzat@hotmail comAbstractDeep drawing is the most important process for forming sheet which is used widely in industry for changingthe form of metal sheets and convert it into hollow parts and without any seam This process has wide use inproducing parts with different forms and sizes for different aspects of production which covers many smallparts and useful in electrical and electronic industry with sizes up to few meters in variety industries Specialmethods in processing of deep drawing have caused improvement in industries such as airplane and carproduction Wrinkling is considered one of main defects of deep drawing process and is a problem which we areconfronted in this process This defect can cause damages to die and bad effect on part and its capability therefore prediction and prevently in wrinkling is very important This project has tried to consider different parameters effect on wrinkling phenomenon of square cups inprocessing of deep drawing The kind of material which is used in aluminum and blank circling All simulations has done with ABAQUS EXPLICIT v6 7 software and effects on different aluminum alloys punch radius matrix radius blank holder force blank holder gap and friction coefficient on wrinklingphenomenon The results of this research has concluded that with increase of blank holder force increase offriction coefficient decrease of blank holder gap decrease of punch radius and matrix radius can decreasedthe wrinkling in deep drawing process Also the concluded results has compared with practical results Key WordsForming deep drawing wrinkling aluminum alloys abaqus software
