1.) Define viscoelastic, hysteresis, creep, force relaxation, energy absorbed, energy
returned, elastic region, plastic region and yield point in a stress - strain curve.
2.) Describe the properties of a viscoelastic material.
3.) Give examples of biological tissues that are viscoelastic.
4.) Explain the time dependent response of a viscoelastic material.
5.) Explain the rate dependent response of a viscoelastic material.
6.) Draw a stress-strain curves for elastic, ductile and brittle materials. Label elastic region,
yield point, plastic region, and failure point.
7.) Draw a stress – strain curve for a cancellous (spongy) and cortical bone.
8.) How does velocity (rate of loading) affect the response of the spring and damper
(dashpot) in a viscoelastic material?
9.) Explain the difference between creep and force relaxation.
