Dr. Evan J. Pineda is a Research Aerospace Engineer in the Multiscale and Multiphysics Modeling Branch, Materials and Structures Division at the NASA Glenn Research Center. Dr. Pineda has over 13 years of professional experience at NASA in the area of multiscale modeling of heterogenous materials with a focus on progressive damage and failure analysis. He is the lead developer for the NASA Multiscale Analysis Tool (NASMAT) being developed under the Transformational Tools and Technologies (TTT) program in support of the “Vision 2040: A Roadmap for Integrated, Multiscale Modeling and Simulation of Materials and Systems.” Throughout his entire career, he has served as an expert on damage tolerance and fracture control for NASA’s heavy lift launch vehicles and is currently working on the Space Launch Systems (SLS) Universal Stage Adapter (USA) project. Currently, he is also developing multiscale models for semi-crystalline thermoplastics for the Thermoplastics Development for Exploration Applications (TDEA) for welded composite joints in a space environment, Cryotank Technology for Exploration Applications (CTE-A), and a joint project with the Office of Naval Research (ONR) focused on Tailored Universal Feedstock for Forming (TuFF) composites. Dr. Pineda has authored, or co-authored, over 200 technical publications and has given four plenary or keynote conference lectures and 12 invited university seminars. He was awarded the Presidential Early Career Award for Engineers and Scientist (PECASE) in 2019 which is the “highest honor bestowed by the U.S. government on outstanding scientists and engineers beginning their independent careers,” and most recently won the ASME-Boeing Best Paper Award for a AIAA SciTech 2021 conference paper.

Abstract : NASA Multiscale Analysis Tool

Virtual testing is important for the development of advanced materials and structures. Multiscale modeling enables physics-based simulation of materials and structures incorporating the relevant phenomena at the appropriate length scale. The NASA Multiscale Analysis Tool (NAMSAT) serves as a state-of-the-art, “plug and play,” massively multiscale analysis (MMA) platform for hierarchical materials and structures utilizing high performance computing (HPC). NASMAT supports multiscale analysis spanning an arbitrary number of length scales. Moreover, the micromechanics theory deployed at each scale is also arbitrary, allowing for variable fidelity within the multiscale hierarchy and resulting in computationally efficient simulations. NASMAT contains a library of constitutive laws and damage theories, enabling fully-integrated (homogenization and localization), non-linear analysis of materials and structures. Multiscale structural analysis is achieved through interoperability with 3rd party finite element software, and it has been demonstrated that NASMAT is capable of solving industrial-sized engineering problems (500K+ multiscale elements). In this presentation, an overview of multiscale modeling and the NASMAT software architecture is presented along with scaling performance on HPC. In addition, several examples are presented including validation of the micromechanics theories, failure predictions of 3D woven composites, prediction of the thermoelastic properties of thermoplastics polymers, non-linear modeling of dry fabrics, simulation of polycrystalline metals and simulation of a full-scale ceramic matrix composite turbine vane.
