Bone is viscoelastic because it exhibits both viscous (flow-like) and elastic (recovery-like) properties when subjected to load. The organic matrix (collagen) provides elasticity, allowing bone to deform and return to its original shape, while the mineral component (hydroxyapatite) provides stiffness. The combination of these components results in bone's viscoelastic behavior, which enables it to withstand various mechanical stresses.
Viscoelastic solids return, for the most part, to their original shape when a substantial applied shear load is removed. Viscoelastic fluids do not. This distinction does not have a clear boundary as viscoelastic materials all have both fluid and solid properties.
Viscoelastic behavior is the combination of viscous (fluid-like) and elastic (solid-like) properties in a material. When subjected to stress, a viscoelastic material will exhibit both elastic deformation (instantaneous response) and viscous flow (time-dependent response). This behavior is commonly seen in polymers, biological tissues, and some fluids.
Yes, memory foam has the ability to absorb shock due to its viscoelastic properties. When pressure is applied, memory foam reacts by contouring to the body and absorbing the impact, making it an excellent material for absorbing shocks.
the only movable bone is the mandible (jaw)
The viscosity of rubber varies depending on its composition and temperature. Generally, rubber has a high viscosity, meaning it resists flow and deformation. Rubber can exhibit both elastic and viscous properties, making it a viscoelastic material with complex rheological behavior.

Maxwell and Voigt models can describe viscoelastic properties of bone by considering it as a combination of springs (representing stiffness) and dashpots (representing viscosity). In the Maxwell model, the spring and dashpot are arranged in series, showing fast initial response followed by relaxation. In Voigt model, the spring and dashpot are arranged in parallel, showing both elastic and viscous responses simultaneously. This can help understand how bone behaves under mechanical stress, exhibiting both elastic deformation (spring-like) and viscous damping (dashpot-like) characteristics.
