Abstract

A method is presented for evaluating stresses and displacements in multiply layered media based on the Fourier complex variation principle. Basic solutions are specificallv presented for a three layer model of seam extraction from which surface slopes, curvatures and body strains may be recovered. Subiect to the initial assumptions of linear elasticity, zones of potential fracture are predicted based on empirical strain based failure criteria.
