摘要:
In this paper, we introduce a factorization of the equilibrium equation in the theory of Toupin-Mindlin strain-gradient elasticity in the framework of quaternion analysis by using the inframonogenic operator Fu = DuD and the Dirac operator of mixed sides D(a)u = cos a Du + sin au D, where D is the Dirac operator in R-3. We construct some integral representation formulae for the displacement fields. In application, we obtain a decomposition formula of the displacement fields.
