Development of deep learning-based joint elements for thin-walled beam structures

This study presents a new modeling technique to estimate the stiffness matrix of a thin-walled beam-joint structure using deep learning. When thin-walled beams meet at joints, significant sectional deformations occur, such as warping and distortion. These deformations should be considered in the one-dimensional beam analysis, but it is...

Rendering 6-DOF Object-to-Object Interaction with 3-DOF Haptic Interfaces

Three degree-of-freedom (3-DOF) tool-based haptic interfaces are widely used in virtual environment to train operators, and for virtual prototyping and design. In some special cases with higher requirement on haptic fidelity, the tool needs to be modeled as an object with real volume rather than a single point. However, such object -to-object...
