Abstract

A finite element simulation study is carried for cold working process ON 2024·T351 aluminum
alloys plate. During the process the load is transferred by A mandrel to the plate. which tries to
bend a portion of the plate and affects the formation of residual stresses resulting from the cold
working process. It is observed that non-dimensional radial residual stress for entrance face and mid thickness plane at the edge of the hole is affected a little by the start of support distance i.e. for various support conditions. Whereas, the tensile radial residual stress for the exit face reduces considerably from a value of 1.05 to approximately zero , The non-dimensional tangentlal residual stresses for the entrance decrease with start of support distance. Whereas, the non-dimensional tangential residual stresses for the mid plane and exit face reduce from higher compressive stress to tower compressive stress.
