In continuum mechanics, and in particular in finite element analysis, the Hu-Washizu principle is a variational principle which says that the action

∫ V e [ 1 2 ϵ T C ϵ − σ T ϵ + σ T ( ∇ u ) − p ¯ T u ] d V − ∫ S σ e T ¯ T u   d S

is stationary, where C is the elastic stiffness tensor. The Hu-Washizu principle is used to develop mixed finite element methods. The principle is named after Hu Haichang and K. Washizu.
