abstract={This work considers the analysis and derivation of dynamical equations on rectangular plates governed by micropolar continuum theory.

These derived equations are hyperbolic and can be constructed in systematic fashion to any order desired. Hence it is believed that these sets of equations are asymptotically correct.

AB This work considers the analysis and derivation of dynamical equations on rectangular plates governed by micropolar continuum theory. The proposed method is based on a power series expansion of the displacement field and micro-rotation field in the thickness coordinate of the plate. This assumption results in sets of equations of motion together with consistent sets of boundary conditions. These derived equations are hyperbolic and can be constructed in systematic fashion to any order desired. Hence it is believed that these sets of equations are asymptotically correct. The construction of the equation is systematized by the introduction of recursion relations which relates higher order displacement and micro-rotation terms with the lower order terms.
