A ductile crack starting from a hole grew stably with mixed mode fracture which combined tensile mode and shear mode fracture, and the nondimensionalized growth rate of crack for strain increment was proportional to nondimensionalized crack size l/D independent of the hole shape, which can be written as d(l/D)/dε∝l/D where l is crack length, D is the diameter of a specimen and ε is the true strain. Hence, the extension behavior of a ductile crack depends on crack size in this investigation. The ductile fracture originated in a surface is different from the cup-and-core type in macro-scopic features.","subitem_description_type":"Other"},{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_30002_file35":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"kaneshiro_h20.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2000798/files/kaneshiro_h20.pdf"},"version_id":"caee3c4a-5d9a-4086-bb04-a14d8154c7c5"}]},"item_30002_identifier16":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/210"}]},"item_30002_language12":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_30002_publisher10":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"日本機械学会","subitem_publisher_language":"ja"}]},"item_30002_resource_type13":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_30002_rights6":{"attribute_name":"Rights","attribute_value_mlt":[{"subitem_rights":"Copyright (c) 1988 日本機械学会","subitem_rights_language":"ja"}]},"item_30002_source_identifier22":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"03875008","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN0018742X","subitem_source_identifier_type":"NCID"}]},"item_30002_source_title23":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_source_title":"日本機械学会論文集.
