But modeling the forces involved in such processes is a huge computational challenge that often takes days to weeks to solve.\u0026nbsp;Now, engineers at the Massachusette Institute of Technology\u0026nbsp;and Georgia Tech have found a faster and simpler way to model intrusion through any soft, flowable material. \u003Ca href=\u0022https:\/\/physics.gatech.edu\/user\/daniel-goldman\u0022\u003EDaniel Goldman\u003C\/a\u003E, Dunn Family Professor in the \u003Ca href=\u0022https:\/\/physics.gatech.edu\u0022\u003ESchool of Physics\u003C\/a\u003E, joined MIT researchers\u0026nbsp;for this project.\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":"","uid":"34434","created_gmt":"2023-01-23 16:27:46","changed_gmt":"2023-01-23 16:27:46","author":"Renay San Miguel","boilerplate_text":"","field_publication":"","field_article_url":"","publication_url":"https:\/\/news.mit.edu\/2023\/soft-push-granular-intrusion-0119","dateline":{"date":"2023-01-19T00:00:00-05:00","iso_date":"2023-01-19T00:00:00-05:00","tz":"America\/New_York"},"extras":[],"groups":[{"id":"1278","name":"College of Sciences"}],"categories":[{"id":"150","name":"Physics and Physical Sciences"}],"keywords":[{"id":"4896","name":"College of Sciences"},{"id":"166937","name":"School of Physics"},{"id":"12040","name":"Daniel Goldman"},{"id":"185542","name":"Massachusetts Institute of Technology"},{"id":"176087","name":"intrusion"},{"id":"667","name":"robotics"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
