Abstract: Canonical equations of elasticity and its corresponding variational principle are presented,a Hamilton element and a semi-analytical numerical method are developed,and finally two numerical examples are given,i.e.a deep beam and a laminated thick orthotropic plate.

Key words: elastodynamics, hamilton element, thickwall-laminated structure
