The Cosserat couple modulus for continuous solids is zero viz the linearized Cauchy-stress tensor is symmetric

摘要

We investigate weaker than usual constitutive assumptions in linear Cosserat theory still providing for existence and uniqueness and show a continuous dependence result for Cosserat couple modulus mu(c) -> 0. This result is needed when using Cosserat elasticity not as a physical model but as a numerical regularization device.
