Modelling of material parameter uncertainty of resonance wood used in violins using the Interval Field

The interval field method can be used to model spatial uncertainty in finite element models. When analysing spatial uncertainty, dependency is an important quantity to consider, as it is physically implausible to assume a quantity is independent in locations that are close to each other. The interval field method was introduced to join this concept of dependency with classical interval analysis, omitting the need to define probability distributions. This paper will apply the theory of interval field (IF) to the dynamical properties of a violin top plate, with uncertain stiffness and density.
