Penetration experiments were then carried out for shaped charge jets having a single inactive (Cu) liner or an inactive\/active (Cu\/Al) double-layer liner with variable liner height. The behaviors and firelight patterns of the different jets were captured by high-speed photography. The perforation, deformation area, and deflection were measured for each plate, showing that the Cu\/Al jets have stronger PE effects. Numerical simulation shows that the tip of the composite jet generated from the full-height liner is only Cu, whereas for the other jet, from the double-layer liner, Cu is almost wrapped entirely by Al.<\/jats:p>","DOI":"10.3390\/ma15010344","type":"journal-article","created":{"date-parts":[[2022,1,7]],"date-time":"2022-01-07T01:14:02Z","timestamp":1641518042000},"page":"344","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["The Penetration\u2013Explosion Effects of Differently Distributed Inactive\/Active Composite Shaped Charge Jets"],"prefix":"10.3390","volume":"15","author":[{"given":"Jiacheng","family":"Peng","sequence":"first","affiliation":[{"name":"State Key Laboratory of Explosion Science and Technology, Beijing Institute of Technology, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianwei","family":"Jiang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Explosion Science and Technology, Beijing Institute of Technology, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianbing","family":"Men","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Explosion Science and Technology, Beijing Institute of Technology, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinlin","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Explosion Science and Technology, Beijing Institute of Technology, Beijing 100081, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongkang","family":"Zhou","sequence":"additional","affiliation":[{"name":"Anhui Fangyuan Mechanical & Electrical Co., Ltd., Bengbu 233000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuan","family":"Hu","sequence":"additional","affiliation":[{"name":"Anhui Fangyuan Mechanical & Electrical Co., Ltd., Bengbu 233000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2098","DOI":"10.48084\/etasr.1532","article-title":"A Review of Works on Shaped Charges","volume":"7","author":"Ahmed","year":"2017","journal-title":"Technol.
