Abstract: Systems and method are provided for predicting an expected mechanical property, such as fatigue strength, for a component with a cellular structure or a portion thereof. In some embodiments, a method for predicting fatigue strength includes receiving, by a control circuit, image data for a specimen to reconstruct 3D models of the specimen. The specimen includes at least one cell of a cellular structure. The method further includes determining a local stresses for the specimen via finite element analysis of the three-dimensional models. The control circuit may then determine a fatigue strength for the specimen based on the local stresses to generate a distribution function of the fatigue strength for the at least one cell of the cellular structure. The control circuit then applies statistics of extremes to the distribution function to predict an expected fatigue strength of a number of cells in the cellular structure.
