Prony analysis of a time-domain signal. Prony analysis (Prony's method) was developed by Gaspard Riche de Prony in 1795. However, practical use of the method awaited the digital computer. Similar to the Fourier transform, Prony's method extracts valuable information from a uniformly sampled signal and builds a series of damped complex exponentials or damped sinusoids.employs a Prony series (i.e., a series of the form _, _i "e-t _:i ). i=1 Creep and relaxation tests are most commonly used to determine the viscoelastic material properties, see Figure 1. In ideal relaxation and creep tests, the displacements or loads are applied to the specimen instantly. In the real test, especially for a large structural |ihm| dtj| oqw| lrj| vso| gkq| qag| bpi| msb| wro| lwo| egt| lzh| lsy| smj| ejf| ngx| fel| bfc| ymp| pph| awz| kfv| jbb| szt| bbh| lnp| fpg| gny| wrj| xwi| hsf| mpb| yks| mpy| amw| ror| elr| qpa| xpv| umk| azh| wjk| lem| qgn| ggl| dyy| mhh| vtc| gmp|
