Finite Element Analysis

Stresses in Beams and Arches

The upper two figures were created with a photoelastic device using crossed Polaroid lenses. The left figure represents the stress in a post-and-beam design developed by the ancient Greeks. The right design shows stresses in the arch developed by the Romans. By contrast, the lower two figures show the same two designs with stresses calculated by finite element analysis. Red shows the highest stresses while blue shows the lowest stresses.
