Design is a human centred creative approach that transforms and improves organizational capabilities for innovation and strategic decision-making. The aim of this research is to identify the impact of design, in particular ...
Bemrosetta: An open-source hydrodynamic coefficients converter and viewer integrated with Nemoh and Foamm
(EWTEC, 2021)
Boundary Element Method (BEM) solvers are extensively used to obtain the hydrodynamic coefficients required to model hydrodynamic forces in oating marine structures. BEM solvers require the discretization of the submerged ...
Code-to-code nonlinear hydrodynamic modelling verification for wave energy converters: Wec-sim vs. nlfk4all
(EWTEC, 2021)
In the wave energy conversion field, simulation tools are crucial for effective converter and controller design, but are often prone to become very casespecific, in both structure and parameter selection. This is due to ...
Simulation of Cold Forging Processes Using a Mixed Isotropic-Kinematik Hardening Model
(Springer, 2021)
Cold forging is a manufacturing process where a bar stock is inserted into a die and squeezed with a second closed die. It is one of the most widely used chipless forming processes, often requiring no machining or additional ...
High-Speed Material Characterization Using an Instrumented Forging Hammer
(Springer, 2021)
Hammer forging is a widely employed manufacturing process to produce parts with excellent mechanical properties. Although the rheological behavior and the microstructural transformation phenomena of metals under hammer ...
Analysis of the Tool Stick-Out Influence on Machining Chatter
(2021)
Increased stability in machining processes is highly desired by all machining industries when vibrations and specially chatter occur. This phenomenon is defined as a self-excited vibration that occurs due to the regeneration ...
Contact pressure and sliding velocity ranges in sheet metal forming simulations
(2021)
In the last few years many efforts have been carried out in order to better understand what the real contact between material and tools is. Based on the better understanding new friction models have been developed which ...
