dynamic elasticity
3.The Incremental Functional in Nonlinear Elasticity and Dynamic Analysis Theory for Cable Structure of Finite Elastic Deformation
4.From the elasticity variational principle, the governing dynamic differential equations of the geometric non-linear beam with large deflection is deduced.
5.To obtain a hot oil resistant, high elasticity, high strength, rubber-like and easy in processing materials for oil-sealing, NBR/PFPA thermoplastic elastomer was prepared by dynamic vulcanization. The mechanical properties were measured.
6.The paper studied controlling rotor vibration with the super-elasticity of SMA and SFD, set up the new equation of sys tern vibration according to the stress-strain curve of SMA in super-elasticity state, used the nonlinear theory and the dynamic stability theory to study the vibration of rotor controlled by SMA, discussed the stability condition of the system, obtained the relationship of system parameters when bifurcation was appeared, supposed a method that improves the stability of rotor system and restrains vibration amplitude though changing parameters, and finally validated the effect of restraining vibration of the improved system through emulation.
