A computer-based method for evaluating progressive damage in a metal test component includes providing Computed Tomography (CT) image data of the component to a processor and processing the CT image data via the processor, including detecting observable defects in the component. The method also includes characterizing the observable defects into corresponding defect categories, generating a data table of the observable defects and the corresponding defect categories, and embedding a collective set of data from the data table into a finite element model (FEM) of the component to thereby construct a modified FEM of the metal test component. Additionally, the method includes analyzing the modified FEM through an isotropic and/or anisotropic structural model, via the processor, to thereby generate a set of test results. A quality control action is then executed with respect to the metal test component based on the test results.

Progressive damage and failure analysis of metal parts using computed tomography

A method, apparatus, and system for managing a composite structure. A set of component models is created for a set of components in the composite structure. A set of embedded reinforcement element models is placed within the set of component models for the set of components in the composite structure to form a composite structure model for the composite structure. The set of embedded reinforcement element models is for a set of embedded reinforcements embedded within the set of components in the composite structure. A structural analysis of the composite structure is performed using the composite structure model formed by the set of component models and the set of embedded reinforcement element models, wherein the set of embedded reinforcement element models enables modeling at least one of a deformation or a failure of embedded reinforcements.
