Problem 2 In class, we have derived the solutions for stress relaxation and creep tests for...
Harmonic response of the Maxwell element The Maxwell element for modeling a viscoelastic system treats it as a spring and a viscous dashpot connected in series as shown in the diagram below. The red arrows indicate the direction that the stress is applied. E and η are the Young's modulus of the spring and the viscosity of the dashpot component, respectively. Both parameters are real constants and characterize the model completely. dashpot spring (a) Show that the time rate of...
Creep +recovery (recoil) test on viscoelastic tissues We are considering: ơ(t)-Applying a load stress on a piece of tissue ! de(t) dt do(t) dt ODE: Hint: Read Ozkaya, Ch. 15.4, page 225 -227 before you attempt the problem below. Pay attention to Fig 15.11 (a), Fig 15.17, Fig 15.18, and try to understand the physics that he's talking about there !) 1) Using Laplace transforms, find the transfer function H (s)5 a(s) from the numerator of H (s) El ที่...
