Papers abstract:

High velocity sheet metal forming methods, such as electromagnetic forming and electro hydraulic forming (EHF), are based on high voltage electrical energy. This paper gives theoretical details about high strain rate forming in the Electrohydraulic forming process. Following the experimental results in the literature, a simulation of the high strain rate forming was prepared in ABAQUS-CAE wherein a dynamic loading on a sheet blank was applied and was allowed to plastically deform following the Johnson-Cook material model. The results of the simulation were validated from the experimental values obtained from existing literature. After the model was validated, further simulations were carried out to obtain similar results for other commercially available materials like Al 6061 T6 alloy and Mg-Gd-Y alloy.

Product Overview:
This package provides a ready-to-use FEM model for simulating high strain-rate sheet metal forming via EHF, validated against experimental dome heights and strain distributions. Key simulation steps include:

• Dynamic explicit loading with a 100 µs pressure pulse.
• Johnson-Cook material model implementation for strain-rate sensitivity.
• Clamped boundary conditions and surface-to-surface contact modeling.
• Post-processing for dome height, strain distribution, and deformation velocity

In this tutorial, electro-hydraulic free forming of sheet metals is simulated, according to data from the work of Mane et al.
