Abstract:Based on the analogy of structural mechanics and optimal contro1, and a1so based on carrying the minimum potential energy variational principle in elastici- ty to the generalized one, the theory of Hami1tonian system can be introduced into theory of e1asticity and e11iptic PDE. The transverse eigensolutions of the Hamiltonian operator matrix and its expansion solution method can be deduced. Such method can be wide1y app1ied for prismatic domain prob1ems.The method is given in detail through the so1ution of the p1ane elastic prob1em in a strip domain.
Keywords:elasticity  eigenva1ue prob1ems  state-space method/ Hamiltonian system  simplectic
