1. Viscoplasticity is still in a formative stage.

2. In this paper the theory of viscoplasticity is applied for the analysis of sea ice loads, and a mathematical creep model under uniaxial stress condition is generalized to a triaxial formulation.

3. With the advantage of low porosity and strong viscoplasticity, the salt caverns can be used to storage carbon dioxide absolutely.

4. The viscoelasticity and viscoplasticity of bonding material will result in hysteresis and drift errors to sensor output.

5. Based on the constitutive realtion of elastic viscoplasticity, the incremental functional is de- rived by means of non-linear functional analysis theory in this paper.

6. The viscoplasticity theory is suggested to be available to analyze the mechanical behavior of superplastic deformation.

7. The coupling of consolidation time step and viscoplasticity time step can guarantee the program's stability and precision.

7. Wish you will love and make progress everyday!

8. By applying genetic algorithm, multi-parameter identification of time dependent model of elasto- viscoplasticity for rock is achieved with a success.

9. Plastic dashpots reflecting the material transient response and Newton dashpots mirroring the material viscosity are introduced to describe the viscoplasticity of slip systems.

10. With direct B. E. M. the boundary integral equations of soil for elastoplasticity, viscoplasticity cluding creep and temperature stress are researched and soluted.

11. The optimization aimed at decreasing deform force of forging is carried out. Based on rigid viscoplasticity finite element method, the optimization design is studied.

12. Since the traditional step-by-step calculation is avoided, the proposed viscoplasticity framework can be used in the realistic boundary value problems under large number cyclic loading.

13. Have introduced Maxwell model and Kelvin model in the classical model of viscoplasticity theory.
