| Abstract Scope |
As additively manufactured metals move towards structural applications, predictive models of their life are needed. This talk will discuss our recent developments to calibrate and validate fatigue modeling efforts, and in particular in assessing modeling under the unique challenges presented by AM materials, include pore defects, surfaces with relatively complex and difficult to measure topography, and even locally varying microstructures. Key components of such a framework include experimental data representing possible features that impact fatigue life (e.g., XCT scans to show pores and rough surfaces), integration of that data with modeling tools (e.g., XCT-based defect geometry), and finally coupling these to performance measures such as cycles to failure and failure site analysis. |
