Biological systems and their engineering description: the bioengineering approach and description of the link between structure and function in biological systems. Structures and biological materials: tissues, collagen and recruitment theory; mechanical characterization and breakage of biological materials. Stress-time employees: the viscoelastic behavior of the composite and two-phase materials. bone tissues: analysis of the mechanical behavior as a function of the composition and structure. The dynamic response and failure mechanisms healing and remodeling. Soft tissue: structure and mechanical behavior of the collagen-based tissue and proteoglycans such as tendons, ligaments and the dermis. The composite materials models of Maxwell and Voigt. Multiphase tissues: a cartilage models and applications, and intervertebral disc; theories of lubrication applied to the articular cartilage. The linear viscoelastic models of Maxwell, Voigt and Kelvin. vascular tissue architecture of the vessel wall, models for the calculation of the state of the vessels solicitation. active tissues: origin of contractility, the motor protein, the sarcomere, skeletal muscle, cardiac and smooth; the energetics of muscle contraction. Elements of fluid dynamics: viscosity; ideal fluids and viscous fluids; fluid compressible and incompressible fluids; laminar and turbulent flow; the Reynolds number and the number of Womersley; flow in ducts; Bernoulli’s equation; load losses; Poiseuille’s equation; characteristic curves of pumps and circuits; networks lumped. Navier-Stokes equations. Tissue fluids: blood rheology and synovial fluid.
