  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.

This paper presents our study on the effect of fillers on mechanical damping of chlorinated butyl rubber above its glass transition temperature, Tg. In the temperature range of Tg -36℃, the effect of interaction between rubber and fillers on mechanical damping of chlorinated butyl rubber was studied and discussed in terms of several parameters such as the content of combined rubber absorbed on the surface of fillers, surface area of fillers, the interfacial functionψ, and the surface area of fillers occupied by rubber of unit weight.The effect of interfiller friction on mechanical damping of the filled ruber was described with the parameters ψ and φ. φ is the volume fraction of fillers.It is shown by the results that when the content of the fillers is low, the mechanical damping of filled rubber depends on the interaction between the fillers and rubber.On the other hand, the mechanical damping of the filled rubber was improved notably by the friction between the filler particles.

本文研究了填料对氯化丁基橡胶在玻璃化转变温度以上的温度范围里的力学阻尼行为的影响。在T_g-36℃的范围里,通过测定填料表面吸附的结合橡胶和填料的表面积,用填料-橡胶界面积函数和单位重量橡胶在填料表面占据的表面积等参数,研究了填料-橡胶相互作用对氯化丁基橡胶的力学阻尼行为的影响;用界面积函数和填充胶中填料的体积份数之积研究填料-填料相互摩擦对它的力学阻尼行为的影响。发现在填料浓度低时,氯化丁基橡胶的力学阻尼行为主要受填料-橡胶相互作用的影响,高浓度时,填料-填料相互摩擦显著地改善了它的力学阻尼行为。

The effect of EPDM on the mechanical damping and crystallization behavior of PP/LDPE blends are investigated by means of Rheovibron DDV- Ⅱ EA and Perkin Elmer DSC-2C.The Tg of PP in PP/EPDM blends decreases from 15°C to 5°C when the content of EPDM increases to 80% (mass) (Figure 1). The Tg peaks of LDPE and PP in PP/LDPE/EPDM blends overlap each other and shift to lower temperature side with increasing EPDM content (Figure 2). This phenomenon implies that the amorphous phases are compatible with EPDM...

The effect of EPDM on the mechanical damping and crystallization behavior of PP/LDPE blends are investigated by means of Rheovibron DDV- Ⅱ EA and Perkin Elmer DSC-2C.The Tg of PP in PP/EPDM blends decreases from 15°C to 5°C when the content of EPDM increases to 80% (mass) (Figure 1). The Tg peaks of LDPE and PP in PP/LDPE/EPDM blends overlap each other and shift to lower temperature side with increasing EPDM content (Figure 2). This phenomenon implies that the amorphous phases are compatible with EPDM . The αc relaxation peaks of both PP and LDPE in PP/LDPE/ EPDM blends overlap reciprocally and become broad sloping band at 30 - 160 °C . The relaxation is crystal premelting transition . The crystallization of PP in PP/EPDM is impeded by EPDM .The EPDM in PP'EPDM and PP/LDPE/EPDM acts as a crystal center . It is shown that the crystalline temperature (Tc) of PP and LDPE in PP/LDPE/EPDM decreases .TwoTc of PP are found in PP/LDPE/EPDM .The lower TC decreases with increasing EPDM content from 5% to 25% (Table).

用动态粘弹谱仪和DSC研究了聚丙烯/三元乙丙橡胶(PP/EPDM)的动态力学性能,考察了EPDM对PP/LDPE(低密度聚乙烯)的力学行为的影响。结果表明,EPDM对PP有增塑作用,在PP/LDPE/EPDM共混物中,PP和LDPE的非晶部分与EPDM具有部分相容性;PP有两个结晶温度(T_c),较低的一个T_c随共混物中EPDM含量(5~25质量份)的增加逐渐向更低温度区迁移,说明EPDM具有加快冷却速率的作用。
