Definition
| force applied to an object |
|
|
Term
|
Definition
| when an object is changed temporarily (elastic deformation) or permanently (plastic deformation) due to an applied force |
|
|
Term
|
Definition
σ
normalized load
how much load is applied over a certain area of a material |
|
|
Term
|
Definition
Σ
normalized measure of deformation representing displacement between particles in body relative to reference length |
|
|
Term
|
Definition
| amount of deformation a material has to undergo before it starts "holding" a large load |
|
|
Term
|
Definition
strain/stress ratio
the steeper the slope, the stiffer the object |
|
|
Term
|
Definition
stress at which object begins to deform plastically
point "separates" elastic from plastic region |
|
|
Term
|
Definition
| ability of a material to return to its previous shape after stress is released |
|
|
Term
|
Definition
| a means for measurement of the stiffness of material in the elastic region |
|
|
Term
|
Definition
| the amount of load an object can hold/withstand |
|
|
Term
|
Definition
| the permanent deformation of a material due to excessive loading |
|
|
Term
|
Definition
energy loss during cyclic loading and unloading of a material due to the viscoeleastic nature of the tissue
less energy is put back into the tissue during loading that was required during loading |
