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 designation is to describe the general viscoelastic behaviour of bodybuilders (soft tissues) when they subsist windup(prenominal) compression. To pass that we will use the Kelvin model (standard bilinear unfaltering model).This model simulates the two different reactions of the muscle,viscous and elastic,respectively by dashpots and echos . To be more precise,it consists of two systems in par anyel:a) a onslaught and b)another spring with a dashpot in series. ? The spring represents the elastic components of the muscle and obeys hocks constabulary : F=k*x still 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 rightfulness for straight,par whollyel and uniform flow: ?=?* where ?: viscosity and :change of rate of aura (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 farseeing 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 wellspring as k0,k1,? constants and is impossible to solve as they be all unknown. For that reason we will use the experimental data from Bobsbooms given(p) over paper that will help understand how our functions are divinatory(p) to be cons truct during the experiment and thus be ! able to move out nigh data and some important initial and limit point conditions, incumbent for our model to work. From the Bobsbooms paper Passive transverse mechanistic properties of penniless muscle in compression we are supposed to take the ramp and hold data (u versus t graph) and oppose it in our model,expecting that our F versus t graph will have a similar outcome with the second graph below. information from the u versus t graph above:...If you want to locomote a full essay, order it on our website: BestEssayCheap.com
