Therefore, a development of the simple measurement method of crack tip opening and closing is considered to be important for the evaluation of crack propagation. In this study, for an elastic-plastic condition in a center-cracked plate, it is proposed that the crack tip opening and closing point can be simply determined with the σ-(ε_y-α)/(ε_x+α) diagram and σ-ε_y diagram, where σ is the cyclic stress, ε_y and ε_x are the strains measured in the vicinity of the crack center by means of a strain gauge and a is a constant value. Then this measurement method is compared with results obtained by finite element method calculations.","subitem_description_type":"Other"},{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"日本機械学会","subitem_publisher_language":"ja"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/214"}]},"item_1617186920753":{"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_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_source_title":"日本機械学会論文集.
