Data driven modeling of plastic deformation
WebFatigue properties under axisymmetric push-pull loading of a magnesium alloy Mg-6Zn-0.5Zr (ZK60) after processing by multiaxial isothermal forging (MIF) to a total strain of 4.2 at 400 °C were investigated. The strong influence of the microstructure on the mechanical behavior is demonstrated. Hot severe plastic deformation was shown effective in improving the … WebData-driven Haptic Modeling of Plastic Flow via Inverse Reinforcement Learning Abstract: Most of the natural and man-made objects that we daily encounter undergo permanent or plastic deformation when the applied force exceeds a certain limit. Furthermore, we frequently use this material property to shape objects to desired forms.

This paper presents a novel data-driven model for predicting the plastic hinge length of reinforced concrete columns and its implementation in force-based fiber beam-column elements.
WebSep 29, 2024 · Also, the training data are generated from a small strain-formulation model, 12 thus limiting the CP-SM to predict microstructure evolution only at small plastic deformation. The current model can be further improved and extended by directly implementing some of the physics in the model, by augmenting the training data with a … WebApr 5, 2024 · It is known as plastic deformation in which an object is permanently deformed. It happens when bonds between atoms are broken, and new ones are formed, making the reversal to original shape impossible. How much force is applied on the object (stress) is directly proportional to the object’s dimensions (strain).
