Biomechanics
A resident is preparing for the biomechanics viva examination. The examiner asks about fundamental mechanical properties of orthopaedic materials and the relationship between stress and strain. Regarding stress, strain, and Young's modulus:
Mark each as TRUE or FALSE
Stress is defined as force per unit area (σ = F/A) and is measured in Pascals (Pa) or Newtons per sq...
Young's modulus (E) is the ratio of stress to strain in the elastic region (E = σ/ε) and represents ...
Young's modulus and stiffness are the same thing; they are both intrinsic material properties that d...
In the elastic region (Hookean behavior), stress is proportional to strain and the material returns ...
Approximate Young's modulus values: cobalt-chrome 230 GPa, stainless steel 200 GPa, titanium alloy 1...
