Product Overview:

Springback refers to the geometric changes that occur in a part once it is released from the forces exerted by the forming tool at the end of the forming process. In sheet metal forming, both deep-drawn and stretch-drawn parts experience springback, which can significantly impact the dimensional accuracy of the finished product.

1. Predicting Final Geometry: Accurately forecasting the final geometry after springback is crucial for ensuring dimensional precision in manufactured parts.
2. Tool Design Considerations: Manufacturing tools must be designed to compensate for the springback effect, addressing the practical challenges faced in production.

In this video, we study the simulation and investigation of the springback phenomenon during the deep drawing process. The approach includes:

1. Deep Drawing Process Simulation: Initially, the deep drawing process is modeled using an explicit method to accurately capture the forming stages.
2. Springback Analysis: Following the deep drawing simulation, a static method is used to analyze springback. The results from the last increment of the deep drawing process serve as the initial conditions for the springback section.
