  • Roughness: deviation of a real surface and its ideal shape.
  • Stencil: node arrangement used to pass information through a numerical solution to a differential equation.
  • Strain: measure of relative displacement between particles in a continuous material body; deformation of the material. Note the distinction between finite and infinitesimal strain theory.
  • Strain rate: change in strain over time.
  • Taylor Series: representation of a continuous function as the sum of an infinite series of terms. The terms are derivatives of the function at a point.
