应变张量不变量对张量的导数怎么求?是多少?

I1 = first principal invariant of M,
e-K;AVX I2 = second principal invariant of M,
)`^ zuu1N I1 = third principal invariant of M,
`9D?)O"S
p)MH0De then what is the derivative d(I1)/d(M)? and d(I2)/dM? and so on?h"hL7lH

WvG8{ VXr Thank you for help

比较复杂,你可以参考《张量分析》(黄克智著)的P122。
