Aircraft Structural Integrity Program (ASIP) Conference

SwRI will be exhibiting at the ASIP Conference, booth no. 4.

Southwest Research Institute^® (SwRI^®) is an independent, nonprofit, applied research and development organization that has supported Aircraft Structural Integrity Programs for more than 40 years. Our work in the field spans the entire range of ASIP tasks including in-flight recording of aircraft loads; static strength, finite element, and damage tolerance analysis; inspection and repair option development; corrosion prevention and control; and developing the digital thread processes to document all of that for the fleet. We provide a complete range of testing, such as detailed metallurgy and fractography, material property tests, and full-scale aircraft static and fatigue tests. We also lead development of NASGRO®, the most widely used fatigue crack growth software in the world, which includes fracture mechanics models for more than 100 different structural configurations. Our array of ASIP engineering services supports all types of aircraft structures and landing gear.

Please join us for the following presentations:

Thursday, Nov. 19

9:00 a.m. – 9:30 a.m.
“In-Situ Monitoring Driven Defect and Microstructure Twins to Inform Microstructure-Based Life Predicitons of Laser Poweder Bed Fusion AM Components,” James Sobotka

We are working on a new approach to estimate the lives of additively manufactured metal components. It combines advanced in-situ sensors, defect and microstructure twins, and microstructure-based lifing to determine the unique lives of parts coming off of a laser-powder bed fusion machine.

10:30 a.m. – 11:00 a.m.
“What Can the FALSTAFF Spectrum Do for You?” Jon Walker

The FALSTAFF Spectrum was developed in the 1970s to provide a spectrum that could be used across different aircraft and organizations without sharing sensitive information. But how does it compare to other legacy aircraft spectra? In this presentation, we discuss how it compares and where it fits in the DTA community today.

2:30 p.m. – 3:00 p.m.
“Probability of Detection of Fatigue Cracks for Throughwall Inspection with In718 Repair Bushings,” Nathan Richter

This talk will summarize a recently completed project that constructed Probability of Detection (POD) curves for a through-bushing eddy current inspection of aircraft bolt holes. The POD effort was designed per the recommendations of MIL-HDBK-1823A to determine the a90/95 flaw sizes, which describe the largest corner crack that could be missed from an inspection. The talk will also discuss the manufacturing of specimens, the setup of the inspections, and the efforts to generate additional POD predictions based on interpolations of experimental results.
