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 contro! circuit, image data for a specimen to reconstruct 3D models of the specimen. The specimen includes at least one celi of a cellular structure. The method further includes determining a locai stresses for the specimen via finite element analysis ofthe three-dimensional models. The contro! circuit may then determine a fatigue strength for the specimen based on the locai stresses to generate a distribution function ofthe fatigue strength for the at least one celi of the cellular structure. The contro! 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.

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 contro! circuit, image data for a specimen to reconstruct 3D models of the specimen. The specimen includes at least one celi of a cellular structure. The method further includes determining a locai stresses for the specimen via finite element analysis ofthe three-dimensional models. The contro! circuit may then determine a fatigue strength for the specimen based on the locai stresses to generate a distribution function ofthe fatigue strength for the at least one celi of the cellular structure. The contro! 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.
