Abstract
The present paper analyse the main characteristics of the numerical simulation by finite element method of the deep-drawing processes. Also the authors’ highlights the mathematical apparatus and the calculus method used for numerical simulations of metal forming processes in many of the current simulation software. The authors present the capabilities of the inverse analysis, direct analysis, implicit analysis (for springback simulation) and the optimisation analysis applied to explicit formulations.
Highlights
Metal forming technologies can be applied in a wide range of areas in the machines manufacturing industry, in fine mechanics, electro technics and electronics, the consumer goods industry etc. due to their technical-economic advantages: efficient usage of materials and energy, increase in productivity and manufacturing efficiency etc.The current worldwide economic development is generated by a virtual explosion based on the implementation of sheet metal forming technologies instead of the classical machining technologies
The elaboration of new sheet metal forming technologies involves the usage of modern techniques for the computer-aided design of products and tools, simulating the forming process with the help of the finite elements method, adaptive process control, usage of numerical control machine-tools etc
A short description of the mathematical apparatus and of the calculus method used for numerical simulations of metal forming processes will be made, indicating the manner in which this problem is tackled in most current calculation software packages
Summary
Metal forming technologies can be applied in a wide range of areas in the machines manufacturing industry, in fine mechanics, electro technics and electronics, the consumer goods industry etc. due to their technical-economic advantages: efficient usage of materials and energy, increase in productivity and manufacturing efficiency etc.The current worldwide economic development is generated by a virtual explosion based on the implementation of sheet metal forming technologies instead of the classical machining technologies. The analysis of metal forming using the finite elements method in the nonlinear domain presents a series of particularities that will be discussed in the following.
