Abstract

From the extended energy functional,a unified variational rinciple an extended variational principle^*, is given and proved in this aher. It is about the nonconservative, abrupt and divuied domains static (or kinetic) system, Using the undetermined energy functional, we can immediately deduce various variational princiales.
