Effect of H-doping on damping capacity of various NiTi-based alloys at kHz frequencies
Article Abstract:
The effect of H doping in combination with various thermomechanical treatments given to materials, in order to identify conditions for maximum efficiency in the conversion of mechanical energy into heat at around room temperature was studied. It was observed that for appropriate alloy composition, the peaks occur at around room temperature (for acoustical frequencies), providing an opportunity to reduce machinery vibrations and noise pollutions.

Modeling foam damping materials in automotive structures
Article Abstract:
Foam damping materials can reduce vibration amplitudes in automotive structures. Their mechanical properties depend on foram homogeneity, temperature, frequency of excitation and degree of expansion. There are standard methods to determine mechanical properties, including Young's modulus. Analysis of free vibrations and forced response of a hood is provided, together with test data showing the accuracy of the structural model.

Enhancing damping of aluminum using SiC and/or Ge
Article Abstract:
The design of dynamic mechanical systems for mechanical components is actively sought with the help of metallic material with enhanced stiffness and damping characteristics. The experimental observation of this enhancement in damping characteristics is rationalized in terms of microstructural changes such as the presence of plastic zones at the matrix reinforcement interface.
