For the reduction of numerical effort and processed data in numerical stress analysis, the present paper is focused onto the investigation of an efficient method for the a priori detection of a structural component’s highly stressed areas. Based on the theory of stress mode superposition and the frequency domain solution of the decoupled equations of motion, an analytically consistent approach for a priori mode superposition is presented. In this context, the influence of multiaxial loading and mode normalisation is investigated. Validation is performed on a simplified industrial model of a twist-beam rear axle.
