We were honored to have Jason Action from Lockheed Martin present at the SIMULIA Americas Users Conference, May 1-2, 2024 in Novi, Michigan.

Abstract: Lockheed Martin’s Advanced Development Programs’ Star Drive initiative has been advancing the integration of design and analysis tools to streamline the overall process and amplify the digital thread. Project Gamma, a part of the Star Drive initiative, has used Dassault’s 3DExperience platform to advance the utilization of the generative design and analysis capabilities. This project has also increased LM’s capability to develop and perform Abaqus analyses within the platform as part of an overall generative design workflow. In developing and executing Abaqus models, the need to utilize non-standard keywords as part of the analysis can be a major enabler. This is often performed by injecting text edits to an input file before the analysis is initiated, which is an interruption to an integrated workflow and thus the digital thread. This presentation will highlight some of the work completed on Project Gamma to utilize inpRW to initiate a Virtual Crack Closure Technique (VCCT) analysis of a composite double cantilevered beam from within the platform. The goal is to integrate the necessary alterations to the analysis within the platform and maintain the digital thread between the analytical model and parent geometry.

Bio: Jason Action is an Aeronautical Engineer at Lockheed Martin for the past 21 years. His focus is in structural analysis and finite element modeling ranging from full air vehicle models down to detailed part models. He has used Abaqus extensively over the course of his career, performing and helping to develop progressive damage analysis methods on composite parts and joints.
