Visualization of Von Mises criterion trend by means of a color-coded map describing tensions intensity scale. Blue indicates lowest tensions, and red the highest. Color values for intermediate intensities are interpolated from cyan, green, and yellow a. Stress distribution on the chin area induced by Delaire FM (external and interior side). Intermediate tensions in green were observed at the level of the upper border of the chin and tended to decrease as moving away from this area. b. Stress distribution on the forehead area induced by Delaire FM (external and interior side)
