Based on the analyses the extensive use of nonferrous sheet metals in modern industry and the current research situation of the aligning technology, this paper extends the problem lying on aligning the sheet metal of nonferrous metals.

Study on typical rupture modes of thin metal plates under normal impact by conical-nosed missiles;

According to the electromagnetic wavetransmitting equation in good conductor,get the eddy currents 'heating power in sheet metal,then some factors that affect heating power are di-scussed.

In order to study the laws and mechanisms of plasma arc forming,an experimental investigation was performed with 1Cr18Ni9Ti and Q235 sheet metals scanned forward and backward by moving it with respect to the stationary plasma arc.

In this paper,the characters of flexible forming of sheet metal using plasma arc are introduced,and its mechanism is analyzed.

Instead of the rather complicated analytical method and computer aided numerical method for solving two dimensional steady state heat conduction problem of perforated metal sheets this paper proposes an electroconductive paper based thermoelectrical analogy method.

1～8《Sheet metal formability and test methods》were a set of standards for sheet metals forming and their metallurgical industry,which might be divided into three parts.
