- Continuous function One that is everywhere differentiable. Also in Wikipedia
- Deviatoric stress: difference between the full stress and the spherical stress in a volume
- Explicit numerical scheme: calculates state of a system at a future time using its state at the current time. The discretized function of the dependent variable with respect to the space domain involves only the current time.
- Implicit numerical scheme: discretized function of the dependent variable with respect to the space domain involves the future time.
- Liklihood: measure of the relative frequency with which an hypothesis can explain observations
- Monte Carlo sampling: repeated random sampling
- 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
- Uncertainty: indistinguishable interpretations of observational data
