TitanX is strengthening its numerical simulation capabilities. As part of this process, we are looking for two additional FE Analysts.
Neil Stephen, Professor of Structural Mechanics at the University of Southampton and editorial board member of the International Journal of Solids and Structures has received the first Doak Prize for an outstanding journal paper On Energy Harvesting from Ambient Vibration (JSV, 293,1/2, pp 409-425).
The sources of noise in a vehicle are many, including the engine, driveline, tire contact patch and road surface, brakes, and wind to name a few. A Noise, Vibration, and Harshness (NVH) engineer is tasked with predicting these noises early in the design phase to make the necessary adjustments to ensure a harmonic ride, so to speak. The latest SIMULIA Tech Brief illustrates the effects that rolling tires have in contributing to NVH.
The Piezoelectric Device Laboratory has immediate opennings for recent PhDs. We are engaged in researchs in piezoeelctric acoustic wave resonators with supports from government and indsutry. The Laboratory has been grwoing and we would like to have new members to accelerate the pace and expand collaborations with the fast growing piezoelectric acoustic wave device industry in China and other countries.

Hi,
I have to use Hamilton pricinple to evaluate the diff. equation of motion of a string. As shown in the figure below, the string is hanged from one end and is free at the other. The flexural stiffness of the string is negligible.
I have a problem with the potential energy of the string! required in the Hamilton principle. Since the flexural stiffness of the string is assumed to be negligible, is there any other term for potential energy?
