**ABSTRACT:**

The main aim of this article is to derive the dynamical equations of an elastic body by extending the concept of symmetric components to the concept of asymmetric components of stress tensor, and extending the concept of stress vectors to the couple of stress vectors and then extending the concept of stress tensors to the couple stress tensors; and also extending the concept of deformation into the concept of micro-deformation in theory of elasticity.

**Key words:** Strain tensor, Stress tensor, Micro-rotation vector, Couple stress tensor, Micro-strain tensor, Stress moments.
