Finite Element Analysis is a powerful tool creating and analysing the physical behaviour of computational models. To compare the behaviour of vertebrate structures that differ in size and shape, every analysis requires standardization of the initial conditions of the model. In this paper we present a new procedure adapting two-dimensional models of vertebrate structures to easily compare them only modifying the value of the biomechanical forces applied. This approach is shown to be extremely useful when exploring the effect of the shape in front of the strength and the stiffness of vertebrate bone structures that can be simplified to two-dimensional models.
