Abstract：
|
|
Based on the theory of plastic instability of sheet,a theoretical formula for caculating the plastic instability is derived out with the influence of in-plane directionality of n-value on FLCs in dif- ferent directions counted in,and corresponding theoretical FLCs are established.Experimental FICs have also been established for verifying the correctness of theoretical analysis.
