Fig. 5.

A comparison of maximum principal strain orientation (tension) between experimental and finite element (FE)-derived results. Minimum principal strains (compression) occur orthogonal to the illustrated axes. Axes drawn on the mandible are averaged from experimental trials; axes drawn to the left or right of each figure illustrate the comparable FE model strain orientation. Numbers refer to the relevant jaw experiment or model. Number identifiers are only illustrated for the experimental data when orientations differ markedly. (A) Dorsal dentary; (B) ventral dentary; (C) lateral surangular; (D) medial surangular.
