Multiscale modeling of steel fiber reinforced concrete based on the use of coupling finite elements and mesh fragmentation technique
(Computational Modelling Of Concrete Structures. Euro-c 2018, 2018-01-01) [Trabalho apresentado em evento]
A multiscale model is proposed based on the use of coupling finite elements recently developed by the authors. This feature allows the use of the same strategy to deal with two problems of non-matching meshes addressed in ...
Monitoring of Self-Excited Vibration in Grinding Process Using Time-Frequency Analysis of Acceleration Signals
(2018 13th Ieee International Conference On Industry Applications (induscon), 2018-01-01) [Trabalho apresentado em evento]
Grinding is a finish manufacturing process for high precision parts. As the part has high value added at this stage, anomalies and defects are unacceptable. Self-excited vibration or just chatter is an undesirable and ...
