The proposed methodology for determining fracture toughness involves characterization of the evolution of torque with the degree of rotation for a number of test cases performed with specimens having different lengths of the ligaments between the notches. The work is supported by measurement of the in-plane and gauge length strains in aluminium AA1050-H111, and the overall experimental results show that the new proposed test provides an easy and effective way of evaluating the ability of a sheet metal to resist cracking under in-plane shear loading conditions. <\/jats:p>","DOI":"10.1177\/0309324715576429","type":"journal-article","created":{"date-parts":[[2015,4,1]],"date-time":"2015-04-01T15:18:41Z","timestamp":1427901521000},"page":"221-231","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["A new test for determining fracture toughness in plane stress in mode II"],"prefix":"10.1177","volume":"50","author":[{"given":"Isik","family":"Kerim","sequence":"first","affiliation":[{"name":"Institute of Forming Technology and Lightweight Construction, Technical University of Dortmund, Dortmund, Germany"}]},{"given":"Maria Beatriz","family":"Silva","sequence":"additional","affiliation":[{"name":"IDMEC, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Lisboa, Portugal"}]},{"given":"AG","family":"Atkins","sequence":"additional","affiliation":[{"name":"Department of Engineering, University of Reading, Reading, UK"}]},{"given":"AE","family":"Tekkaya","sequence":"additional","affiliation":[{"name":"Institute of Forming Technology and Lightweight Construction, Technical University of Dortmund, Dortmund, Germany"}]},{"given":"Paulo AF","family":"Martins","sequence":"additional","affiliation":[{"name":"IDMEC, Instituto Superior T\u00e9cnico, Universidade de Lisboa, Lisboa, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2015,3,31]]},"reference":[{"key":"bibr1-0309324715576429","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijmecsci.2014.04.003"},{"volume-title":"Elastic and plastic fracture: metals, polymers, ceramics, composites, biological materials","year":"1985","author":"Atkins AG","key":"bibr2-0309324715576429"},{"key":"bibr3-0309324715576429","doi-asserted-by":"crossref","unstructured":"Keeler SP.
