Figure 1.Finite element model of Allosaurus fragilis skull. Elements are represented by each individual triangle. Geometric equations can be used to calculate strain and stress in simple structures. FEA permits the application of these geometric equations to complex, nongeometric shapes by calculating stress/strain in each individual element. (Reprinted with permission, © Emily Rayfield)
Figure 2.FEA-generated stress plot of skull in Fig. 1. A color-coordinated map of stress distribution within the structure may be produced from a FEA. Strain maps, vector plots, and displacement values are produced in a similar fashion. Here color and white areas of the mesh represent increased compressional stress.
