摘要:
研究了不可压缩材料平面非线性弹性力学中能量函数的凸性,证明了目标各向同性弹性能量$W$在特殊线性群$\mathrm{SL}(2)$上的秩一凸性蕴涵了$W$的多凸性.
英文摘要:
We study convexity properties of energy functions in plane nonlinear elasticity of incompressible materials and show that rank-one convexity of an objective and isotropic elastic energy $W$ on the special linear group $\mathrm{SL}(2)$ implies the polyconvexity of $W$.
