弹性力学混合状态方程的弱形式及其边值问题

WEAK FORMULATION OF MIXED STATE EQUATION AND BOUNDARY VALUE PROBLEM OF THEORY OF ELASTICITY 1)

  • 摘要: 导出了弹性力学混合状态方程和边界条件弱形式的统一方程,此法使函数的选择无需事先完全满足边界条件,对于各种不同的边值问题可以用统一形式处理,这使得求解弹性力学问题的形式得以扩大和统一

     

    Abstract: Prof Tang clarified importance of mixed state equation of elasticity, and first gave Hamilton canonical equation by modifying Hellinger-Reissner variational principle At the same time author pointed out that the study of solution of mixed state equation has still not been well developed though it has a wide spread application prospect.This is because Hamilton equation must satisfy comples boundary condition in continuous medium mechanics which is its difficult point, Fan and Ding applied the mixed sta...
