Open AccessLos mecanismos que rigen la densificación de los materiales granulares durante su compactación son fuertemente dependientes de los estados de tensión y deformación en las zonas de contacto entre partículas. Un modelo ...

Open AccessIn this work, a Plasticity model for granular materials, based on the Drucker-Prager/CAP model, is applied to represent the behaviour of the metallic powders during their cold die compaction. The elastic deformation has ...

Master thesis (pre-Bologna period)
Restricted access - author's decisionTIG welding is a very clean welding, and produces high-quality welds. But usually it’s performed manually, so that the quality of weld depends on the skill of the operator, and there’s not so much theoretical information ...
Restricted access - publisher's policyThe demand for powder metallurgy (P/M) parts in its traditional automotive market is predicted to grow, but future sector expansion depends directly upon its capability to manufacture zero-defect parts for industries such ...
Restricted access - publisher's policyTribological behaviour of two 3Y-TZP materials (polycrystalline zirconia stabilized by 3% of yttria) with different heat treatments (i.e. different grain size) has been studied using ball-on-disc technique in dry conditions ...
