报告摘要：In this talk, I will introduce a new computing paradigm: data-driven smoothed meshfree method, where the data are directly from experimental material data and pertinent constraints and conservation laws. This method avoids the empirical modeling step of conventional computing. Data-driven solvers aim to find the state satisfying the conservation laws that is closest to the data set. The resulting data-driven problem thus consists of the minimization of a distance function to the data set in phase space subject to constraints introduced by the conservation laws. I investigate the performance of data-driven solvers by means of two examples of application, namely, the static equilibrium of nonlinear three-dimensional trusses and linear elasticity. I also illustrate the robustness of data-driven solvers with respect to spatial discretization.
