Stress Mode Superposition for a Priori Detection of Highly ‎Stressed Areas: Mode Normalisation and Loading Influence

Stress Mode Superposition for a Priori Detection of Highly ‎Stressed Areas: Mode Normalisation and Loading Influence

From the economic and technical point of view, the reduction of development periods and required resources represent a considerable benefit. For the reduction of numerical effort and processed data in numerical stress analysis, the present paper is focused onto the investigation of an efficient meth...
