Finite element (FE) simulation of grained material with equiaxed grain distribution is of interest for the virtual prototyping of array structures and the assessment of signal processing algorithms. Construction of such models can be computationally intensive due to the large number of crystallographic orientations required to represent the material. This paper concentrates on analysis and processing...
A combination of asymptotic approach and computational modeling is used for solution of problem to investigate the backscattering of several small particles embedded in fluid medium. The initial diffraction problem of wave scattering by many small particles is developed under the assumption ka ≪1, d ≫ a, where a is the size of the particles and d is the distance between the neighboring particles....
We report on the design and experimental validation of a distributed Brillouin-based optical fiber sensor embedded into concrete structures for temperature and strain measurement. A composite-made wave-like coating designed by finite-element analysis ensures the sensor is transferring optimally temperature and strain fields from the concrete to the optical fiber, where Brillouin scattering takes place...
