, Fysica
Viscoelasticiteit van biologische materialen en
lichaamsvloeistoffen
- Elasticiteit:
 Wet van Hooke: F=kDx
o Uitrekking en compressie
o Buiging
o Afschuiving
o Torsie
 Elasticiteit vd stof
o Elasticiteitsmodulus E (Pa)
 Kracht nodig om materiaal tot dubbele lengte uit te rekken


o Stress (σ of Dl/l)
 Materiaalspanning
o strain (ε of F/O)
 relatieve rek
 O=opp
o σ = E* ε
 afschuiving (shear)
o shear stress (τ)
 afschuifspanning
o shear strain (γ = tan thèta)
 afschuiving
o τ =G* γ
 vervormingsspanning evenredig met relatieve vervorming

- Energie in elastische media
 wissel tussen potentiële en kinetische E

o =
o Keert terug naar oorspronkelijke toestand + mechanische E behouden
o Vb achillespees
 Potentiele elastische E komt vrij als kinetische E

- Stress-strain curves
 Na bepaalde vervorminggeen terugkeer meer
