In order to reasonably depict four basic problems with friction, one Coulomb friction new form in first Kirchhoff stress is proposed to deal with finite deformation problems, other Coulomb friction form in incremental mode to elastoplastic flow theory; Hilbert function spaces concerning elastoplastical problems with friction are established, so it makes all operations and calculations in the treatise standardized within the scope of reasonably topologic structure; In view of functional extremum, the equivalence between generalized variational inequalities principles in elastoplasticity with friction and corresponding basic problems are testified by inducing Lagrangian multipliers, so it provides a rationally theoretical basis for numerical methods in elastoplasticity with friction; From the viewpoint of variational inequality, the theory of generalized variational inequalities in elasticity and elastoplasticity with frictional constraint is studied, and the uniqueness and existence of the solution of FEM is proofed under the proposed conditions of stress compatibility, and them FEM approximation and a discrete solution are discussed; Based on the principles of generalized variational inequalities in elastoplasticity with friction, direct generalized variational inequalities methods is pretended, which is a natural generalization and development of direct variational methods; Using generalized variational inequalities methods, some examples in metal forming including plane deformation, upset and extrusion are analyzed and the results prove that all the theories and methods in the paper are right, feasible, accurate and advanced.

This article takes the Marxism Humanics and Western Stimulation theory as its foundation stone .It also takes the Marxism Humanics as its guide thought and philosophical foundation which constitute the Stimulation Management Mode . Through reflecting on the traditional Stimulation Mode and studying the logical foundation of stimulation of teachers in elementary and middle schools ,we deeply reflect on the Tradition Stimulation Mode and its thought and attribute the problem of stimulation strategy to the loss of the humanity and the pinch of the value pursuit .From the reality of Chinese culture and modern school culture .we use the essential thought in the Western Stimulation Theory for reference and set a definition on Stimulation from the philosophical view ,that is ,the subject takes the corresponding stimulation mode according to the understanding of the stimulated object needs ,acts on the motivation ,purpose and action of the stimulated and consequently satisfy the purpose of the subject .
