Abstract：
|
|
The general concept,technical kinds and test methods were defined and explained on the formability of sheet metal,the idea was summarized,i.e.,the formability of sheet metal was the appearance of sheet metal forming qualities.According to the development of digital technology,the basic thinking of mathematical methods for physics and the views on modem manufacture and system engineering,the virtual formability concept were set up and the appearance of engineering field function and system engineering were sketchily described on the formability of sheet metal.Therefore,the technique based on the new concept was founded for revising GB/T 15825《Sheet metal formability and test methods》.
