Elastic Dynamics Variational Principle for Nonlinear Elastic Body

  • Received Date: 1990-12-21
  • Publish Date: 1992-01-15
  • Based on paper [1],the variational principle and generalized variational principle of elastic dynamics for elastic body with nonlinear stress-strain relations are introduced in this paper.The generalized instantaneous variational principle is also raised for the mixed harmonious displacement element and the mixed harmonious stress element.
