Severe plastic deformation as a processing tool for strengthening of additive manufactured alloys
(Elsevier, 2021-08)For the first time, the novel combination of multi-pass equal channel angular extrusion/pressing (ECAE/P) and selective laser melting (SLM) was investigated. Herein, four passes of ECAP via route Bc at 150 °C were applied ... -
Silver patterning using an atomic force microscope tip and laser-induced chemical deposition from liquids
(AIP Publishing, 2012)This article presents a new direct patterning technique in which laser photoreduction of silver from a liquid is controlled by a scanning atomic force microscope tip. Contrary to expectations, the tip suppresses, rather ... -
Simplified transfer function approach for modeling frequency dependency of damping characteristics of rubber bushings
(Sage, 2019-09)Physical systems that consist of parts and vibration isolators such as rubber bushings are usually modeled in multibody simulations, where parts are represented as rigid bodies with their mass and inertia properties and ... -
Simulation and analysis of a TET-walker robot motion
(IEEE, 2014)Tetrahedral walker robots are a group of reconfigurable robots which makes them adaptable for the full spectrum of activities in places that wheeled robots are inapplicable. In this paper, two different gaits for a ... -
