3D-printed platform multi-loaded with bioactive, magnetic nanoparticles and an ...
Saraiva, Ana S.; Ribeiro, Isabel A. C.; Fernandes, Maria H.; Cerdeira, Ana Cláudia; Vieira, Bruno J.C.; Waerenborgh, João Carlos; Pereira, Laura C.J.Polymeric platforms obtained by three-dimensional (3D) printing are becoming increasingly important as multifunctional therapeutic systems for bone treatment applications. In particularly, researchers aim to control bacterial biofilm on these 3D-platforms and enhance re-growing bone tissue, at the same time. This study aimed to fabricate a 3D-printed polylactic acid platform loaded with hydroxyapatite (HA), iro...

Numerical study of fatigue crack initiation and propagation on optimally design...
Baptista, R.; Cláudio, Ricardo; Reis, L.; Madeira, JFA; Freitas, M.A new generation of smaller and more efficient biaxial fatigue testing machines has arrived on the market. Using electrical motors these machines are not able to achieve the higher loads their hydraulic counterparts can, and therefore the cruciform specimen needs to be optimized Following the authors previous work, several different optimal specimens' configurations were produced, using the base material sheet ...
Design optimization of cruciform specimens for biaxial fatigue loading
Baptista, Ricardo; Cláudio, Ricardo; Reis, L.; Guelho, I.; Freitas, M.; Madeira, J. F. A.In order to correctly assess the biaxial fatigue material properties one must experimentally test different load conditions and stress levels. With the rise of new in-plane biaxial fatigue testing machines, using smaller and more efficient electrical motors, instead of the conventional hydraulic machines, it is necessary to reduce the specimen size and to ensure that the specimen geometry is appropriated for th...
