New Interactive Animations for Analysis of Stress, Strain, and Flow

In geological investigations, stress, strain, and flow in structures are commonly analyzed with the aid of Mohr Diagrams. This paper presents new alternative constructions that build on the techniques familiar to structural geologists from the use of stereonets. The constructions avoid many of the complexities of previous methods, such as off-axis Mohr circles and poles, and present vector data (such as the stress vector acting on an inclined plane) in the correct spatial orientation. The relationship between new and existing constructions is easily demonstrated. The constructions are animated in the electronic version of this paper and may be viewed with a web browser using Macromedia Flash 5.
