设n≥2是一个整数,ΩCℝn是具有光滑边界⌈=∁Ω的有界域。我们把Ω看作弹性张量C(X)=375-1的弹性介质的参考构型域。我们假设C(X)满足下列超弹性和强凸性条件:(超弹性) $${C_{{ijkl}左(x 右)={C_{{ijkl}左(x 右),对于上划线{Omega,}{ext{}}中的所有x,1行i,j,k,L行n$$ (1.1) 。
Let n ≥ 2 be an integer and Ω C ℝ n be a bounded domain with smooth boundary ⌈ = ∁Ω. We consider Ω as a reference configuration domain of an elastic medium with elastic tensor C(x) = 375-1 We assume that C(x) satisfies the following hyperelasticity and strong convexity conditions: (Hyperelasticity) $$ {C_{{ijkl}}}left( x ight) = {C_{{ijkl}}}left( x ight),forall x in overline {Omega ,} { ext{ }}1 leqslant i,j,k,l leqslant n$$ (1.1) .
