Finite Element Simulation Outputs for Dual Twist Channel Angular Extrusion

128.9 MB of simulation data from a study comparing the Dual Twist Channel Angular Extrusion (DTCAE) process to Equal Channel Angular Pressing (ECAP). The dataset includes outputs from 3D Finite Element Method simulations run in DEFORM-3D, analyzing plastic deformation and strain distribution. It was authored by Vikash Ranjan and uploaded in April 2026.

Use Cases

• Analyze velocity vectors and effective strain contours to compare deformation uniformity between DTCAE and ECAP processes.
• Model load-stroke responses from simulation outputs to predict the force required for the DTCAE extrusion.
• Use simulation data in GEO, KEY, or PROB files to validate or calibrate new finite element models of twist-based extrusion.
• Study strain distribution patterns across different billet sections using contour data from RST or DAT files.

Strengths

• Dataset contains 128.9 MB of simulation data across multiple file formats.
• Simulations model a specific 90° twist and 110° channel intersection geometry for direct comparison to ECAP.

Limitations

• The number of simulation runs or rows of data is unknown.
• Dataset includes over 50 distinct file extensions, indicating a complex, non-standardized file structure that may complicate parsing.
