摘要
A locally conservative hybridized method for planar pure displacement elasticity problem is introduced. To avoid locking phenomena in numerical solutions we consider a mixed formulation by using an artificial pressure variable. By the nature of the hybridization approach, the artificial pressure is determined completely by the local Dirichlet data on the primal variables; hence, there is no increase of degrees of freedom in the global discrete system. A complete numerical analysis is provided and numerical experiments that confirm our analysis are presented.
