Kelvin Model-Viscoelastic Behaviour Of Muscles

M.Sc. Bioengineering 2011-2012 Musculosketetal biomechanics engagement ALTOKA ERATO (PAC:11266318) Option V (Kelvin model) The aim of this appointment is to describe the general viscoelastic behaviour of bodybuilders (soft tissues) when they subsist windup(prenominal) compression. To secure that we will use the Kelvin model (standard bilinear comforting model).This model simulates the two different reactions of the muscle,viscous and elastic,respectively by dashpots and echos . To be more than precise,it consists of two systems in par anyel:a) a forswear and b)another spring with a dashpot in series. ? The spring represents the elastic components of the muscle and obeys plucks constabulary : F=k*x exactly in terms of stress the equation turns into : ?=?*? where ?: employ stress, E:Youngs Modulus of the material ?: extend to. ? The dashpot represents the viscous components of the muscle and is expressed in differential form by Newtons police force for straight,par on th e wholeel and uniform flow: ?=?* where ?: viscosity and :change of rate of sieve (velocity).

The important equations that argon used in this model be: ? F=F1+F0 where F0=k0*u and F1=?1*u1=k1*u1 ? u=u1+u1 After foresighted calculations we finally communicate the differential equation of motion for a standard linear solid: The equation contains F, df/dt ,u ,du/dt functions as fountainhead as k0,k1,? constants and is impossible to solve as they ar all unknown. For that reason we will use the experimental data from Bobsbooms devoted over paper that will help understand how our functions are mantic(p ) to be pose during the experiment and thus ! be able to protract nigh data and some important initial and leaping conditions, incumbent for our model to work. From the Bobsbooms paper Passive transverse machinelike properties of penniless muscle in compression we are supposed to take the ramp and hold data (u versus t graph) and crack it in our model,expecting that our F versus t graph will have a similar outcome with the second graph below. data from the u versus t graph above:...If you want to stimulate a full essay, order it on our website: BestEssayCheap.com
