Matches in DBpedia 2016-04 for { ?s ?p "Cesar Augusto Sciammarella (born August 22, 1924) has made significant contributions to the field of experimental mechanics. In the last decade he has extended his pioneering developments in moiré, holography, and speckle interferometry methodologies down to the nanometric level. These efforts have resulted in the field of optics to go beyond the classical Rayleigh limit reaching the nanometer range and in the electron microscopy to resolutions of the order of atomic distances.His fundamental research is widely used for 3D reconstruction, and stress and strain analysis. In his Doctoral Thesis on the Moiré method he extended the Continuum Mechanics model originally developed by Dantu to large deformations. He developed fundamental equations on the properties of moiré fringes, signs conventions. Furthermore he applied the moiré method to the solution of a plasticity problem, this was the first complete analysis of a non elastic problem with the moiré method. Dr. Sciammarella generalized the concept of fringe order in methods that measure displacements using Fourier analysis in the process of formation of the fringe images. He proved formally that the orders could be represented by real numbers instead of integers as it was usual at the time of his publication. In 1966, he presented a full model of the moiré fringes as phase modulated signals and provided a method to obtain displacements and strains for moiré and photo-elastic fringes. He introduced for the first time in the literature the Fourier method as a tool for fringe pattern analysis. His model stands today as a standard model used in the fringe analysis methodology."@en }
