vibrations

Additive manufacturing of metal alloys yields great potential for the aerospace industry (and others) as it allows the generation of geometrically complex structures with high specific strength, low density and high corrosion resistance. For example, General Electric has demonstrated the possibility of printing titanium fuel injectors for their LEAP engine, Boeing incorporated more than 300 printed parts in their 777X airplane … For such critical applications, the structural quality of printed parts is of utmost importance. Small deviations in print conditions, e.g.

Hi everyone,

I have a Ph.D. in mechanical engineering and seek a postdoc position on vibrations.

My research interests mainly include:

• Vibrations
• Gear vibrations
• Vibration-based fault diagnosis
• Modal analysis and testing

I would appreciate it if anyone would inform me about an open or a potential position soon.

I can share my CV with you in case needed. 

I wanted to bring attention to the very important Fontanela et al recent results in vibrations of cyclic structures like in turbine engines.

A ``small'' but interesting riddle from the basic theory of vibrations. Haven't run into it in any physics/classical mechanics text/reference.
