Extension of Blind Signal Processing,rains on the surface of high-strength steel plates are measured using stereo image correlation (DIC). The stress–strain relation after the necking is obtained from the load and strains by inverse problem analysis using the virtual field method. The stresses obtained by the proposed method are well b

Data Analysis and Application Study, are driven into limit cycle oscillations using an external constant power laser source and coupled via mechanical linkages. As the input laser power is increased, the oscillators transition from a state of synchrony to a state of bistability that manifests as irregular oscillations in the experimen

Joint Approximate Diagonalization Method,s initiated when the tympanic membrane (TM) transfers acoustic waves from the air into mechanical vibration. The information pertaining to TM shape is essential to the expansion of our understanding of the middle ear. This will allow for better hearing protection, clinical diagnosis, and treatment o

Independent Component Analysis,mic strain rate experiments. Aluminum 6061-T6 is tested in tension and compression and recorded using both the high-speed extensometer and a high-speed camera, and the resulting images are analyzed for sample strain and compared to strains found via 1D wave theory calculations. The results show good

Miura Ori metamaterial has been analyzed with static loads, while from the dynamical side, the studies have been conducted with analytical/numerical techniques. The authors analyze this subject and propose

Independent Component Analysis,-field information, with high confidence, and with a very limited instrumentation. Furthermore, advances in camera technology, particularly on resolution and data transfer rate, are now opening the door to new application, such as modal analysis and testing on rotating components. In this chapter, w

Extension of Blind Signal Processing,th the lowest density. Intense research activity has been devoted to the understanding and modeling of the abrupt twinning phenomenon. A particularly challenging aspect of twinning is its abrupt coordinated proliferation across the polycrystalline aggregate. Macroscopically, these events are akin to

Independent Component Analysis,obscured by nesting, interpenetration, and overlapping of tows and laminas. Digital image correlation (DIC) may be used in single-layer tension tests to accurately reveal the complex strain fields of woven composites, and the time-resolved damage onset and evolution of transverse cracking. However,
