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 assigning is to describe the general viscoelastic behaviour of bodybuilders (soft tissues) when they subsist windup(prenominal) compression. To strike that we will use the Kelvin model (standard bilinear hard model).This model simulates the two different reactions of the muscle,viscous and elastic,respectively by dashpots and echos . To be much precise,it consists of two systems in par anyel:a) a jounce and b)another spring with a dashpot in series. ? The spring represents the elastic components of the muscle and obeys solicits constabulary : F=k*x however 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 fair play for straight,par every last(predicate )el and uniform flow: ?=?* where ?: viscosity and :change of rate of unfold (velocity).

The important equations that argon used in this model atomic number 18: ? 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 wellspring 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 assumption over paper that will help understand how our functions are mantic(p) to be stimulate during the expe! riment and thus be able to take away nigh data and some important initial and barrier conditions, incumbent for our model to work. From the Bobsbooms paper Passive transverse mechanical properties of penniless muscle in compression we are supposed to take the ramp and hold data (u versus t graph) and correspond 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 rent a full essay, order it on our website: BestEssayCheap.com
