Metals and polymers generally have favorable responses to such extreme conditions, and are therefore useful in shock absorbing material applications, such as automotive or body armor. There is, however, a limited understanding of the dependence of spall strength, i.e., resistance to dynamic tensile failure, on typical mechanical properties such as hardness, toughness, strengths, and elastic moduli. The proposed work is aimed at determining the relationship between these properties, henceforth referred to as \u0026ldquo;proxy\u0026rdquo; properties, and spall strength, with the goal of developing a predictive model for identifying dynamic tensile spall strengths of metals and polymers.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe specific research tasks will involve employing various methods for collecting\/generating a database on spall strengths and proxy properties of metals and polymers through literature survey, plate-on-plate impact experiments, and computational simulations. Potential proxy properties will be correlated to spall strength through data analytic methods. The main objective will be to develop a set of materials design guidelines that can be used to understand the fundamental mechanisms of how metals and polymers fail under high strain rate impact, i.e., dynamic tensile loading, and to predict the spall strength properties of untested materials.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"\u201cDesign of Materials Tolerant to Spall Failure at High Strain Rates"}],"uid":"27707","created_gmt":"2021-07-13 17:08:17","changed_gmt":"2021-07-13 17:08:17","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2021-07-27T16:00:00-04:00","event_time_end":"2021-07-27T18:00:00-04:00","event_time_end_last":"2021-07-27T18:00:00-04:00","gmt_time_start":"2021-07-27 20:00:00","gmt_time_end":"2021-07-27 22:00:00","gmt_time_end_last":"2021-07-27 22:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
