A strategy to fast determine Chaboche elasto-plastic model

WebTable 2 presents Chaboche parameters identified for the bolt material. As an example, a comparison of the relaxation and Chaboche model for austenitic bolt material is shown in Fig. 4. It can be ... WebDespite its availability for nearly ten years as of the time of this writing, the Chaboche model has enjoyed limited popularity, in part because of the perceived complexity of calibrating the material parameters.

[ 20] determined the model parameters for 316 stainless steel through manual curve-fitting of different expressions to five stabilized cyclic hysteresis loops. However he acknowledged that “automatic identification procedures could be used”. WebThe parameters determined using the above procedure through the genetic algorithm software and used in the simulation of a broad set of cyclic responses are listed in Table 1 below.
