Elastic strain



- Discussion:
    - stretch appied to an object which when removed will allow object to revert to its original resting length without permanent deformation;
    - produces a linear "stress/strain" slope;
    - yield point or limit or proportionality, denotes end of elastic region of the curve;
    - if any load along this gradient up to this point is removed, substance will regain its resting shape;
    - elastic limit: maximum load that a substance can withstand and still resume its original shape
    - elastic modulus of stainless steel is 12 times EM of cortical (EM of titanium is 6 times of cortical bone)
