Project Overview
In this Abaqus tutorial, the Incremental Sheet Forming (ISF) process is simulated. ISF is a flexible sheet metal forming process that can be used to manufacture complex shapes without requiring rigid and dedicated clamping systems.
In this example, an aluminum sheet with a length of 230 mm, a width of 230 mm, and a thickness of 1.5 mm is formed using a forming tool.
Incremental sheet forming process modeled in Abaqus.
Forming Tool and Contact
The forming tool moves over the aluminum sheet and gradually deforms it. The coefficient of friction between the sheet and the tool is defined as 0.15.
The forming tool follows a circular path in the X-Y plane. The continuous movement of the tool gradually changes the shape of the sheet.

Analytical Rigid Surface
The forming die is modeled using a three-dimensional analytical rigid surface. The aluminum sheet interacts with the rigid forming surface during the simulation.
Final Shape of the Sheet
As the forming tool follows its predefined circular path, the aluminum sheet is gradually deformed. The final shape obtained in this simulation is a truncated cone.

Diameter of the Formed Shape
The formed geometry contains circular sections with different diameters. The maximum circle diameter is 194 mm, while the minimum circle diameter is 106 mm.

Advantages of Incremental Sheet Forming
Incremental Sheet Forming allows complex products to be manufactured without using rigid and dedicated clamping systems. As a result, the process can reduce manufacturing costs and production time, particularly for flexible and small-batch manufacturing applications.
