WebMar 13, 2024 · The proposed data-driven computation approach is based on the classical internal variable approach that is used today to describe the material state. However, here the internal hidden variables are not a priori known. There are, however, two particular cases which do not pose any difficulties for us. WebWe emphasize that the local material data sets can be graphs, point sets, ’fat sets’ and ranges, or any other arbitrary set in phase space. Evidently, the classical problem is recovered if the local material data sets are chosen as (10) D e= f( e;˙^ e( e))g; i. e., as graphs in Z e de ned by the material law (4). Thus, the Data-Driven ...
