"Processes to determine the behavior of a visco - elastic material to a temperature.To improve the storage of at least three experimental curves of dynamic parameter of a visco - elastic material, and to define, among a plurality of visco elastic material.At least a visco - elastic material, and apparatus for processing data relating to a visco - elastic material, and to process data relating to a plurality of visco elastic material.The present invention relates to a process for determining the performance of a visco - elastic material at a temperature T ~ W ~, characterised by: (a) n experimental measurements.Where n 5 242, a dynamic parameter P in a function of a deformation Q in each of at least three temperatures t ~ x ~ t ~ y ~,T ~ Z ~ different T ~ W ~ are carried out; (b) for each of said at least three temperatures t ~ x ~ t ~ y ~ t ~ Z ~.The experimental curve passing through all the points that represent the n values experimentally determined in step (a) is plotted; (c) at least 11 values of dynamic parameter P and the defoRmau00e7u00e3o associated Q distributed along the experimental curves fixed in step (b) to the three temperatures t ~ x ~ t ~ y ~,T ~ Z ~ are selected; (d) at least 11 values are selected in relationship (a): b P (Q,T) = a * tu00b2 + b * t + C + (d ~ 1 ~ * tu00b2 + and ~ 1 ~ * t + F ~ 1 ~) * and ^ sym ^ + (d ~ 2 ~ * tu00b2 + and ~ 2 ~ * t + F ~ * and ^ 2 ~) d sym ^ to determine, for subsequent approximations, the values of parameters a, B, C, q ~ 1 ~,Q ~ 2 ~ d ~ 1 ~ and ~ 1 ~ F ~ 1 ~ d ~ 2 ~,F ~ 2 ~ of (a) generating the curves that best approximate the experimental curves fixed in step (b); and (E) the temperature T ~ W ~ and the values of the parameters a, B, C, q ~ 1 ~, q ~ 2 ~ d ~ 1 ~,And ~ 1 ~ F ~ 1 ~ d ~ 2 ~ F ~ 2 ~ obtained in the preliminary stage (d) are inserted in the relation (a) so as to determine the progression of the dynamic parameter P as a function of temperature deformation Q in t ~ W ~.
