NUMERICAL SIMULATION OF INDUSTRIAL SHEET FORMING PROCESSES

Objective


This project resulted in the development of mathematical models and a computational method for the numerical simulation of sheet metal part forming. The combined developments, with additional refinements, are expected to greatly improve the design process and increase the output of stamped parts made from sheet metal.
THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP A COMPLETELY INTERACTIVE SYSTEM FOR NUMERICAL SIMULATION OF TWO AND THREE DIMENSIONAL SHEET METAL FORMING PROCESSES ENCOUNTERED IN PRACTICAL SITUATIONS IN CAN, MOULDING, AUTOMOBILE AND AEROSPACE STAMPING INDUSTRIES.
THIS WOULD INCLUDE THE FOLLOWING MODULES:

A) PREPROCESSING FACILITIES FOR DETAILED DEFINITION OF THE PROBLEM, SHEET AND TOOLING GEOMETRIES, LOADING, BOUNDARY CONDITIONS, MATERIAL DATA AND ALL FURTHER PARAMETERS REQUIRED FOR THE STAMPING OPERATION.
B) ANALYSIS PACKAGE BASED ON THE VISCOUS FLOW AND LARGE STRAIN ELASTO-VISCOPLASTICITY FINITE ELEMENT APPROACHES FOR PREDICTION OF SHEET DEFORMATION, THICKNESS, STRAIN AND STRESS DISTRIBUTIONS, LOAD-DISPLACEMENT HISTORY, MATERIAL FAILURE AND SPRING-BACK EFFECTS.
C) POSTPROCESSOR MODULE FOR PRESENTING THE RESULTS OF THE ANALYSIS IN GRAPHICAL AND DIGITAL FORM SUITABLE FOR USE IN NUMERICAL CONTROL OF THE INDUSTRIAL PROCESS.

IT IS EXPECTED THAT THE SYSTEM DEVELOPED WILL BE DIRECTLY APPLICABLE IN INDUSTRY AS AN EFFECTIVE TOOL TO GUIDE DESIGN CHANGES FOR ACHIEVING BETTER PRODUCTIVITY.
