The stress distribution in rectangular prisms subjected to certain normal end forces on its two opposite faces is a fundamental problem in Applied Mechanics. Reference supplies a method for calculating a symmetric end loading, assuming that the bulk stress on a lateral surface of the rectangular prism is known. Such a measurement could be obtained using advanced thermal emission techniques. The aim of this paper is to extend this concept to the case where an antisymmetric end loading is applied. A method for calculating the bulk stresses for a given antisymmetric end loading is presented in. This will be referred to as the Direct solution. In the Inverse method the end loading will be determined from a known distribution of bulk stress values on a lateral surface. In this case, bulk stresses on the lateral surface will be simulated using the Direct solution.
