A phase-field chemo-mechanical model for corrosion-induced cracking in reinforced concrete [PDF]
arXiv, 2023 We present a new mechanistic framework for corrosion-induced cracking in reinforced concrete that resolves the underlying chemo-mechanical processes. The framework combines, for the first time, (i) a model for reactive transport and precipitation of dissolved Fe2+ and Fe3+ ions in the concrete pore space, (ii) a precipitation eigenstrain model for the ...

Analysis of reinforced concrete beams by the equivalent section method [PDF]
, 2014 This research investigates the analysis of reinforced concrete beams subjected to combined axial load, bending moment and shear force. Cross-sections of general shape are divided, along the height, into plane elements. The biaxial behavior is represented according to the smeared rotating crack approach. Using traditionally accepted hypotheses for beams,

Model-assisted Reinforcement Learning of a Quadrotor [PDF]
arXiv, 2023 In recent times, reinforcement learning has produced baffling results when it comes to performing control tasks with highly non-linear systems. The impressive results always outweigh the potential vulnerabilities or uncertainties associated with the agents when deployed in the real-world.
