In previous studies, the authors showed that the direction of the crack could be controlled by the tensile stress at the induction holes and not by the compressive stress at the SPC hole. We demonstrate that the compression elastic wave changes to a tensile wave when the wave is reflected at the free surface of the induction hole. We also examined the properties of the concrete by developing an elastic wave measuring system that is difficult to break down even in high-temperature, wet, and radiation environment. The elastic wave velocity change in the four concrete types was less than 4%. It was found that the standard deviation value, σ, changed four times. Therefore, it is possible to determine the deterioration of the internal structure of concrete using the standard deviation value σ, which indicates the dispersion of the elastic wave velocity.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Tech Reviews Ltd."}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.32732/jma.2022.11.2.37","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_25":{"attribute_name":"関連リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://doi.org/10.32732/jma.2022.11.2.37"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.32732/jma.2022.11.2.37","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"著作権等","attribute_value_mlt":[{"subitem_rights":"© 2022 by the author(s).
