A new overhang constraint for topology optimization of self-supporting structures in additive manufacturing
(Springer, 2018-11)
This work falls within the scope of computer-aided optimal design, and aims to integrate the topology optimization procedures and recent additive manufacturing technologies (AM). The elimination of scaffold supports at the ...
On the non-proportionality between wheel/rail contact forces and speed during wheelset passage over specific welds
(Elsevier, 2018-01)
This study investigates the influence on the wheel-rail contact forces of the running speed and the shape and position of weld defects along the track. For this purpose, a vertical dynamic model in the space domain is used. ...
A contact mechanics study of 3D frictional conformal contact
(Elsevier, 2018-03)
A contact mechanics study of three-dimensional conformal contact with friction is presented, based on numerical calculations with Finite Element models and an extension of Kalker's exact contact theory which takes into ...
