Abstract
A solution is presented for the stress distribution in a semi-infinite strip subjected to an axial concentrated compressive load. The problem is solved by using the function z = f(w) defining the Schwarz-Christoffel transformation. All the boundary conditions are satisfied except along the two longitudinal edges of the strip. Normal stresses along these boundaries are present which are eliminated by applying the minimum-strain-energy principle at a part of the strip. The stress components are calculated along all the boundaries and the axis of symmetry, as well as along three transverse sections in the neighborhood of the applied load. The theoretical results are compared with experimental results obtained by using photoelasticity and the electrical analogy method for the tracing of isostatics.
