摘要
证明了弹性力学求解体系的微分形式与积分形式的等价关系,建立了统一求解体系构架· 新体系包括微分形式、积分形式及混合形式· 利用微分形式与积分形式的等价关系。
The equivalence between differential form and integral form of a systematic methodology for theory of elasticity is proved. A uniform framework of the systematic methodology is established. New system includes differential form, integral form and mixed form. All kinds of variational principle are proved by the equivalence between differential form and integral form. The idea for generalized virtual work and virtual function is presented.
