Consider as an illustration in Fig. 3.1 a rectangular fracture specimen with large dimensions, isotropic and elastic. Initially the specimen is dashed. With respect to a Cartesian coordinate system \(x_{i}\) and under the action of uniform compressive stress (\(- \sigma {}_{a}\)) along the x1-direction, the specimen shrinks in the x1-direction but extends according to Poisson in the \(x_{2}\) and \(x_{3}\) directions; the shape then taken by the specimen is in solid.
