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

    University dissertation from Stockholm : Universitetsservice US-AB

    Author : Krishnagoud Manda; Anders Eriksson; Ingrid Svensson; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element analysis; articular cartilage defects; knee joint; metal implant; poroelastic; biphasic; TECHNOLOGY Engineering mechanics Other engineering mechanics; TEKNIKVETENSKAP Teknisk mekanik 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

    Abstract : The global trend towards quieter environments has been one of the key topics of acoustics research for years. The recent tightening of the regulations on noise exposure as well as the many reports on the impact of noise on human health confirm this situation and stress ever more the need for innovative mitigation strategies.

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Mathieu Gaborit; Peter Göransson; Olivier Dazel; Émeline Sadoulet-Reboul; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thin layers; numerical methods; FEM; poroelastic materials; couches fines; méthodes numériques; MEF; matériaux po- roélastiques; Teknisk mekanik; Engineering Mechanics;

    Abstract : For quite some time, the strive for more efficient acoustic absorbers keepsincreasing, driven by a number of psycho-physiological studies on health re-lated dangers of noise exposure. As the global wealth increases and with itthe global expectation of quieter living and working environments, manifestedin both politics and research, an important market for sound absorbing andnoise control systems develops in all industrialised countries.
