Data-driven non-linear elasticity: constitutive manifold construction and problem discretization

Abstract: International audienceThe use of constitutive equations calibrated from data has been implemented into standard numerical solvers for successfully addressing a variety problems encountered in simulation-based engineering sciences (SBES). However, the complexity remains constantly increasing due to the need of increasingly detailed models as well as the use of engineered materials. Data-Driven simulation constitutes a potential change of paradigm in SBES. Standard simulation in computational mechanics is based … Show more

“…The data-driven solution could be strongly influenced by the outliers locating near to the physical manifold but do not conform to the hidden material data pattern (or the latent statistical model) of . Without the knowledge of the underlying data manifold, it requires a large amount of data to achieve sufficiently accurate predictions which is costly [20,31].…”

“…Nevertheless, pure data-driven methodology in the area of simulation-based engineering sciences (SBES) [30] is ineffective since in many physical systems well-accepted physical laws exist while useful data in SBES are very expensive to acquire [20,31]. Thus, it is imperative to develop data-driven simulation approaches that can leverage the physical principles with limited data for highly complex systems.…”

“…The method proposed in [18] has recently been extended to static problems with geometrical nonlinearity [26], three-dimensional continua [8], and dynamic problems [20]. Independently, another data-driven approach that makes use of the manifold learning for estimating the material law has been developed [16,17].…”
