“…This behaviour of over and underestimation by the Hertzian theory for soft and rigid films is in agreement with the results recently obtained by Wang et al [2004], where a finite element analysis devoted to finding substrate effects at the nanoscale is presented.…”

This paper presents a methodology for detecting rotor imbalances, such as mass imbalance and crack-induced imbalance, using shaft synchronous vibrations. A vibration detection algorithm is derived based on the first order synchronous vibration response. A detection system was integrated by using state-of-the-art commercial analysis equipment. A laboratory rotor test rig with controlled mass imbalances was used to verify the integrated system. The system was then deployed to an engine subassembly test setup. Four specimens were used in the subassembly test and the test results are reported in the final section.

“…The substrates are therefore layered rather than homogeneous materials. Accounting for the presence of the layer and the substrate beneath it can be important when the layer is thinner and softer than the substrate [14]. Using the mechanical properties of pure silica and silicon provides upper and lower bounds for the actual contact area.…”

“…Probes made of commercial beads using a variety materials with diameters from a few to several hundreds of micrometers and electro-chemically etched probes with diameters from micrometers to several nanometers [14,15] can be easily attached to the force-detecting beam. This broad range of contact forces and probe sizes leads to a spectrum of force constants that can either be calibrated directly or calculated using beam theory.…”

“…Penetration depths in the current study obey this rule. However, more recent work has observed noticeable substrate effects within 10% penetration and claim that the ratio of the indenter radius to sample height must be kept within 10% [41]. The ratio of radius to sample height is 20% in the current study and was implemented to adjust for this limitation.…”

Most brain-injured soldiers do not, however, receive the necessary, rapid brain imaging studies as would their civilian counterparts. Instead they are flown to rear-echelon medical service centers such as in Germany for those studies, as well as additional medical care. There exists, therefore, a critical need for robust brain imaging systems at and near the battlefield. This gap in patient care reduces the quality of care and potentially, therefore the quality of life of injured soldiers. This gap also defines a critical need for rugged, field deployable systems capable of imaging injured brain. For a variety of reasons it is reasonable to expect that changes in the stiffness of brain accompany TBI, and that ultrasound-based 'sonoelastic' imaging modalities responsive to some measure of stiffness might offer a useful means for imaging the changes to brain due to TBI. Use of such systems in and near the field should improve clinical outcome for patients suffering from TBI. Our long-term goal is to develop a field deployable brain imaging system, capable of transcranial application, responsive to brain stiffness.
