The recent and rapid growth of additive manufacturing (AM) and the engineering need for\u0026nbsp;more complex geometries and individualized products has led to a surge of interest in fabricating high-solids loaded particle composites. AM via direct ink write extrusion processes introduces\u0026nbsp;further complexity in fabrication of composites due to formation of process-inherent\u0026nbsp;heterogeneities such as particle aggregation or porosities. The microstructure of such materials\u0026nbsp;varies across different length scales, resulting in processing and mechanical behavior that is often\u0026nbsp;difficult to control and predict.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe shock-compression behavior of heterogeneous particle-filled polymer composites often\u0026nbsp;involves complex interactions, which can make it difficult to predict their dynamic mechanical\u0026nbsp;properties. The shock-compression behavior is often dominated by mesoscale defects (including\u0026nbsp;porosity) or interactions of the shock wave with interfaces and particulates. Traditional diagnostic\u0026nbsp;methods, such as velocity interferometry, enable temporally-resolved measurements, but are\u0026nbsp;limited in spatial resolution and generally provide a volume-averaged response. Spatially resolved\u0026nbsp;measurements are necessary to measure the shock compression properties and provide sufficient\u0026nbsp;information regarding the mesoscale processes which dominate performance of such materials.\u0026nbsp;The goals of the proposed work are: to quantitatively characterize additively manufactured particle\u0026nbsp;composite microstructures, determine their shock compression response, and correlate the\u0026nbsp;observed shock response with the microstructural characteristics of the process inherent\u0026nbsp;heterogeneities.\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Characterization and Effects of Heterogeneities on Shock Compression Response in Additively Manufactured High-Solids Loaded Polymer Composites\u0022"}],"uid":"27707","created_gmt":"2021-11-30 14:40:49","changed_gmt":"2021-11-30 14:40:49","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2021-12-09T12:00:00-05:00","event_time_end":"2021-12-09T14:00:00-05:00","event_time_end_last":"2021-12-09T14:00:00-05:00","gmt_time_start":"2021-12-09 17:00:00","gmt_time_end":"2021-12-09 19:00:00","gmt_time_end_last":"2021-12-09 19:00:00","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":""}}}
