Figure 3 in Cranial mechanics and feeding in Tyrannosaurus rex

Figure 3. Stress in the fused FE Tyrannosaurus rex skull model generated by vertical biting (left column) or tearing (right column). (a) Principal stress 3 [P3], compressive stress; (b) P1 tensile stress; (c) shear stress; (d) P3 compressive stress; (e) P1 tensile stress; and (f) shear stress. Divergent arrows indicate orientation of tensile stress trajectories; convergent arrows indicate orientation of compressive stress trajectories. Units are Pa or Nm‾2. See electronic Appendix C for strain plots.
