Opis

Repetitive Corrugation and Straightening (RCS) process is one of the Severe Plastic Deformation (SPD) techniques which introduces a large amount of plastic deformation in a sheet workpiece without significantly changing its cross-sectional geometry. In present work experimentation and Finite Element (FE) study of Repetitive Corrugation and Straightening (RCS) process is being attempted. The work is done in two parts i.e. Finite Element Study and Experimentation work. In the Finite Element study, the effect of triangular and circular teeth effect has been studied and an intermediate teeth design is used. The teeth are of triangular in shape with a rounded top. Experimentation of RCS process is attempted with a 100mm x 100mm x 1 mm of Al6061 sheet. Experimentation was performed for three cycles of RCS process giving 90° Clockwise rotation along the perpendicular axis to the surface after each pass. Three mechanical tests were performed viz. Micro Hardness test, Tensile test and Stiffness test. To study the effect of the process these tests were performed on processed as well as unprocessed sheet sample. The hardness test shows an increase in hardness after every pass.
