大应变自接触准静态粘弹性

Quasistatic viscoelasticity with self-contact at large strains

Stefan Krömer, Tomáš Roubiček

摘要:

在参考配置(即使用拉格朗日方法),也考虑到在实际变形配置中可能的自接触,在大应变的开尔文-福格特流变学中的框架无关粘弹性被制定。利用二阶非简单材料的概念,证明了一类非简单材料的弱解的存在性,并证明了它们的存在性。通过收敛由隐式时间离散化获得的近似解来显示单射。

英文摘要:

The frame-indifferent viscoelasticity in Kelvin-Voigt rheology at large strains is formulated in the reference configuration (i.e. using the Lagrangian approach) considering also the possible self-contact in the actual deformed configuration. Using the concept of 2nd-grade nonsimple materials, existence of certain weak solutions which are a.e. injective is shown by converging an approximate solution obtained by the implicit time discretisation.
