- The ISH process is an attempt to combine the effect of shot peening with the incremental sheet forming process. It would possibly result in the prevention of microcrack propagation because of the application of compressive forces which can delay the fracture initiation. The obtained results showcase that the fracture depth and wall angle achieved are more in the case of the ISH process compared to that in the ISF process.
- The comparison of both the processes through the strain values shows the higher formability associated with the ISH process compared to the ISF process. Further, it was also noticed that the conical objects are subjected to the plane strain condition.
- In ISF, the deformation mode of a material is a combination of bending, stretching, and shearing. Material deformation in ISH is dominated by direct bending and stretching which limits the reduction in workpiece thickness drastically. As a result of this, the ISH process exhibits a more uniform material thickness distribution as compared to the ISF process.
- The component formed through the ISH process reports better surface quality than the components formed through the ISF process.
- The reduced forming forces were attained while incorporating the hammering in the incremental sheet forming process.
