We crystalize these ideas and the impetus to perform these functions at the pace of innovation as ‘Operationalize Science for Transformational Overmatch’. Simply put, we seek to accelerate discovery and transition breakthroughs to the Warfighter faster than anyone else.Artificial Intelligence (AI) (rule-based and Machine Learning (ML), together) presents powerful new tools for exploring an information landscape in discovering novel materials for applications in extreme conditions (e.g. high-strain rate, high-g loading, high temperature). Such approaches present considerable opportunity in exploring new frontiers for materials used in ballistic applications, especially when coupled with new approaches that allow larger and richer datasets, computational tools, and data infrastructure for collaboration. Broadly, AI/ML can be used to augment individual steps in the synthesis-processing-characterization pipeline, be used for scale-bridging to draw greater information from more tractable experimental approaches, and be used to guide a broader research loop.Advances in synthesis, modeling, and characterization will greatly advance our ability to exploit monolithic materials in extreme conditions. However, there is a need to contemplate how the capabilities of additive manufacturing and other processing techniques can be used to evaluate materials that exhibit spatial variations in composition, anisotropic characteristics, and contain interfaces between multiple materials. The parameter space expands exponentially as these variables compound the system inputs, but truly advanced materials performance will likely be dependent on an integrated systems-level approach to materials design. Application of ML toolsets is viewed as necessary to achieve accelerated discovery of new materials for application in extreme dynamic (impact, thermal, ablative) conditions. ML toolsets and software exist but may need to be adapted for the specific requirements of materials discovery and design. Full exploitation of the ML approach will certainly require extension and further development to focus on proof-of-concept for material classes of interest in ballistic application. This could be achieved within a generalized and scalable framework that supports rapid, robust and trusted data exchange. New tools to consolidate data, and improved high-throughput workflow will require specialized approaches to transient phenomena e.g. shocks, heating, localized deformation, and failure. ML models that incorporate these phenomena will critically rely on physics-based models that target key mechanisms. Critical (targeted by ML approaches) physics models may require further development; ML offers opportunity to consolidate much of these physics into fast-running analytic frameworks compatible with the high-throughput approach and may be used to guide autonomous systems for high-throughput characterization of transient phenomena.To accelerate improvements in Army armor and weapon system performance, DEVCOM-ARL wants to leverage high-throughput methods in synthesis, processing, characterization, and modeling for materials used in these applications. Machine-learning techniques are in the nascent stage of integration with materials science but may present a path towards accelerated discovery, as these tools may uncover novel links between system performance and material science that have been previously underdeveloped or overlooked. DEVCOM-ARL seeks collaboration with external investigators to leverage (and train experts on) machine-learning techniques in the discovery of materials that perform in extreme environments, but machine-learning techniques require large volumes of quantifiable data in order to best reveal links between the materials science and system performance. High throughput techniques may present a viable approach to satisfy the data volume requirements to bring machine-learning to bear.In summary, the US Army Modernization Priorities require materials that survive and perform in extreme environments; harsh military environments of high-acceleration (e.g. projectile launch and flight), high-temperature and rapid ablation (e.g. hypersonic flight), and impacts at very high velocity (terminal ballistics). The totality of these environments and accumulating requirements on future materials drives the imperative to consider an increasingly large number of constituent elements, structure and properties. Discovery must now parse through billions of candidate materials to achieve highly specialized and transformational functions. This drives a data-driven approach; one that fuses high-throughput materials synthesis and characterization with machine learning algorithms and close-loop discovery automation.The overarching goal of this program is to develop the necessary methodologies, models, algorithms, synthesis & processing techniques, and requisite characterization and testing to rapidly accelerate the discovery of novel materials for extreme conditions. As such, it is expected the results of this program will be novel materials exhibiting unprecedented properties that have been developed utilizing all of the aforementioned tools which will be provided to DEVCOM-ARL for further analysis and testing. In order to achieve this paradigm shift in materials discovery, significant advances are needed in the following thrust areas:Data-driven Material Design - meant to be a comprehensive term for all aspects of the material design phase of the material development cycle which are accelerated through the integration of computational methods.High-Throughput Synthesis & Processing – to include both modifying existing synthesis & processing methods to accommodate for high-throughput, as well as developing novel techniques.High-Throughput Characterization – to include implementation of automation, as well as development of surrogate tests to mimic high-strain techniques which are not amenable to automation.ML-augmented Physics-Based Models – the integration of physics-based models with machine learning is poised to be a tipping point in materials science. To date, nearly all ML algorithms have been developed for big data (e.g. image recognition). It is critical that we discontinue ‘repurposing’ these types of algorithms and begin developing ML algorithms specifically designed for materials discovery, and informed by physics.HTMDEC has been developed in coordination with other related ARL-funded collaborative efforts (see descriptions of ARL collaborative alliances at https://www.arl.army.mil/www/default.cfm?page=93) and shares a common vision of highly collaborative academia-industry-government partnerships. However, HTMDEC will be executed with a program model different than previous ARL Collaborative Research/Technology Alliances. Specific components of the program are highlighted below:HTMDEC will be a two-step application process, consisting of a White paper stage and a Proposal stage.HTMDEC will be executed through two funding periods, herein referred to as “Seedling awards” and “Centers”. A Center will be an option period exercised from a seedling award. The only exception to this will be for the FY2022 Targeted Thrust Area FY2022-2 - Data Handling & Management. The Seedling selected for continuation for this particular thrust area will do so as a recurring Seedling for the duration of the HTMDEC program, and will support all of the Centers as the approved data platform for HTMDEC.A FOA Opportunity workshop will be held to brief interested Applicants on the long term program goals of this FOA. In FY2022, only seedling efforts will be awarded. The focus of these seedlings will be to address either one of the FY2022 targeted thrust areas, or one of the primary thrust areas. White papers will address one of the particular thrust areas; thrust areas may change on an annual basis in order to reflect current interests. White papers will be evaluated. Applicants with only the most highly rated white papers will receive an invi
