The experiments are conducted using a fully instrumented impact testing machine. The shape of the deformation of the specimens and the process of initiation and propagation of the material fracture are presented. The obtained force\u2013displacement responses show a good agreement with the simulations performed by the ls-dyna finite element solver. The strain hardening of the material is defined using experimental data of quasi-static tensile tests and the critical failure strain is evaluated by measuring the thickness and the width at fracture of the tensile test pieces. The results show that the absorbed energy to perforate the specimens is highly sensitive to the shape of the striker. Thus, the crack propagation for each striker type is analyzed in terms of the force\u2013displacement response. The failure modes are described by the matrix of the infinitesimal strain tensors and the shape of the deformation of the failing elements.<\/jats:p>","DOI":"10.1115\/1.4030725","type":"journal-article","created":{"date-parts":[[2015,6,2]],"date-time":"2015-06-02T19:30:54Z","timestamp":1433273454000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":6,"title":["Influence of Striker Shape on the Crack Initiation and Propagation on Laterally Impacted Thin Aluminum Plates"],"prefix":"10.1115","volume":"137","author":[{"given":"B.","family":"Liu","sequence":"first","affiliation":[{"name":"Centre for Marine Technology and Engineering (CENTEC), Instituto Superior T\u00e9cnico, Universidade de Lisboa, Lisboa 1049-001, Portugal"}]},{"given":"R.","family":"Villavicencio","sequence":"additional","affiliation":[{"name":"Centre for Marine Technology and Engineering (CENTEC), Instituto Superior T\u00e9cnico, Universidade de Lisboa, Lisboa 1049-001, Portugal"}]},{"given":"C.","family":"Guedes Soares","sequence":"additional","affiliation":[{"name":"Centre for Marine Technology and Engineering (CENTEC), Instituto Superior T\u00e9cnico, Universidade de Lisboa, Lisboa 1049-001, Portugal e-mail:"}]}],"member":"33","published-online":{"date-parts":[[2015,8,13]]},"reference":[{"issue":"1\u20132","key":"2019100616552626600_bib1","doi-asserted-by":"publisher","first-page":"127","DOI":"10.3233\/ISP-2008-0042","article-title":"Simulating the Collision Response of Ship Structures: A Failure Criteria Benchmark Study","volume":"55","year":"2008","journal-title":"Int.
