WebIn our method, the local step P̂G 7→L in (b) is modified. We project an equilibrium state to the closest point on a previously constructed Euclidean space (shown by blue plane) corresponding to the material data space (shown by gray manifold). - "Manifold embedding data-driven mechanics" Web1. Introduction. In this paper, we aim to introduce a field of study that has begun to emerge and consolidate over the last decade—called Bayesian mechanics—which might provide the first steps towards a general mechanics of self-organizing and complex adaptive systems [1–6].Bayesian mechanics involves modelling physical systems that look as if …

Web01. jan 2024. · This article introduces an isometric manifold embedding data-driven paradigm designed to enable model-free simulations with noisy data sampled from a constitutive manifold. The proposed data-driven approach iterates between a global optimization problem that seeks admissible solutions for the balance principle and a local … Web20. jun 2024. · While data-driven model reduction techniques are well-established for linearizable mechanical systems, general approaches to reducing nonlinearizable systems with multiple coexisting steady states have been unavailable. In this paper, we review such a data-driven nonlinear model reduction methodology based on spectral submanifolds. short code 22775
