2. 1. On multilayered system dynamics and waves in anisotropic poroelastic media

   Author : Juan Pablo Parra Martinez; Peter Göransson; Olivier Dazel; Jacques Cuenca; Wennhage Wennhage; Camille Perrot; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; poroelastic media; anisotropy; plane waves; multilayered systems; dynamics; acoustics; optimisation; matériaux poro-visco-élastique; anisotropie; ondes planes; panneaux multicouches; dynamique; acoustique; optimisation; Poroelastiska material; anisotropi; planvågor; flerskiktssystem; dynamik; akustik; optimering; Vehicle and Maritime Engineering; Farkostteknik;

   Abstract : The mechanical and acoustic anisotropy of media is a governing factor in the behaviour of multilayered systems including such media. The understanding of the mechanisms conditioning the dynamic behaviour of multilayered systems is of paramount importance. READ MORE

4. 2. Finite Element Simulations of Biphasic Articular Cartilages With Localized Metal Implants

   Author : Krishnagoud Manda; Anders Eriksson; Ingrid Svensson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element analysis; articular cartilage defects; knee joint; metal implant; poroelastic; biphasic; Other engineering mechanics; Övrig teknisk mekanik;

   Abstract : Articular cartilage is a specialized connective soft tissue that resides onthe ends of long-bones, transfers the load smoothly between the bones in diarthrodialjoints by providing almost frictionless, wear resistant sliding surfacesduring joint articulation. Focal chondral or osteochondral defects in articularcartilage are common and show limited capacity for biological repair. READ MORE

7. 5. Vibro-acoustic modelling of anisotropic poroelastic materials : characterisation of the anisotropic properties

   Author : Christophe Van der Kelen; Peter Göransson; Wim Desmet; Kirill Horoshenkov; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The present-day challenges in the transport industry, steered by the increasing environmental awareness, necessitate manufacturers to take measures to reduce emissions related to the movements of goods and humans. In particular, the measures aiming at a reduced mass or higher load capacity to increase fuel efficiency,  generally deteriorate the noise and vibration insulation properties of their products.
