二维小应变粘弹性

On 2D Viscoelasticity with Small Strain

Zhen Lei

摘要:

通过对变形张量的极式分解,建立了描述Hookean不可压缩粘弹性材料运动的精确二维转动-应变模型。在仅对初应变张量大小作小性假设的情况下,证明了该方程整体经典解的存在性。整体存在性的证明利用了运动的弱耗散机制,这是通过将部分耗散传递给整个系统来揭示的。

英文摘要:

An exact two-dimensional rotation-strain model describing the motion of Hookean incompressible viscoelastic materials is constructed by the polar decomposition of the deformation tensor. The global existence of classical solutions is proved under the smallness assumptions only on the size of initial strain tensor. The proof of global existence utilizes the weak dissipative mechanism of motion, which is revealed by passing the partial dissipation to the whole system.
