  mechanical damping
The piezoelectric ultrasonic composite oscillator technique (PUCOT) has been used to measure the Young's modulus, E, the mechanical damping, Q-1, and the strain amplitude, ε, of a sintered silicon carbide containing pores (Hexoloy-SP).
      
Thermal cycling of the molybdenum- coated intermetallic between 600 °C and room temperature revealed a saturation increase in the modulus with a corresponding decrease in the mechanical damping.
      
An additional goal of the investigation was to determine if any correlation existed between the measured mechanical damping and the fracture toughness of the ductile iron materials; no correlation was found.
      
This article is a study of the mechanical damping of a series of well-characterized ductile iron materials (four separate materials) as a function of strain amplitude, temperature over the range of -100 °C to +100 °C, and magnetic field.
      
Proper design of such components requires a knowledge of the mechanical properties, including how energy is absorbed and dissipated (mechanical damping) by the test material.

Based on the theoretical model of Magnetic Body Force for magnetoelastic interaction of ferromagnetic plates in magnetic fields, and the assumption of quasi-static state to magnetic fields, a theoretical analysis is presented in this paper to the nonlinear dynamic system of a geometrically nonlinear ferromagnetic beam-plate with simply supported and unmovable ends in an exciting transverse magnetic field with periodic variation. First of all, the perturbation technique is employed for analyzing distribution of magnetic fields varying with deflection of the plate. Secondly, a necessary condition of existence of chaotic motions in the magnetoelastic dynamic system is obtained by means of the Melnikov Method. Finally, the chaotic motions of the magnetoelastic system are simulated or searched by the Runge-Kutta method with variable steps, and the Poincaré map and the Liapunov exponents to the trace of motions are employed to evaluate if a chaotic motion appears. The numerical results indicate that there exist some chaotic motions in the magnetoelastic system of the ferromagnetic beam-plates in transverse magnetic fields of periodic varying, and that the chaotic motion is dense when the mechanical damping in the system is small enough in the chaotic range of parameters.

在磁体力分布的磁弹性理论模型和磁场准静态假定模式基础上,对于处在周期时变磁场 中的不可移简支铁磁梁式板非线性磁弹性动力特性进行定性与定量分析.首先利用磁场的摄 动技术和结构变形的模态法,导出了关于模态坐标的非线性动力方程;然后利用Melnikov方 法,从理论上给出这一磁弹性动力系统可能出现混沌运动的必要条件及参数范围;最后采用变 步长Runge-Kutta数值积分方法对其磁弹性相互作用的混沌现象进行了定量搜索与模拟,并 利用其轨迹的Poincare截面图与Liapunov指数加以判断.结果表明磁弹性简支梁式板在横 向周期时变磁场中存在混沌吸引子,且在机械阻尼很小时其混沌吸引子表现出稠的特性.
