Using this set-up, it is found that highly polymerized glass with a lot of bridging oxygens shows more distored microscopic structure under a Vickers indenter than that under a hydrostatic pressure. On the other hand, microscopic structure of de-polymerized glass with non-bridging oxygens is quite different from that under hydrostatic pressure. From in-situ microphotoelastic measurements, it is shown that shear flow in glass under the indenter causes tensile stress around the plastic zone created by the indenter. This is a first experimental confirmation of indentation-induced three-dimensional stress field.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_title":"押し込み「その場」ラマン分光と顕微光弾性解析による破壊直前のガラス構造の直接評価","item_type_id":"40014","owner":"11","path":["1722998947419"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2020-01-07"},"publish_date":"2020-01-07","publish_status":"0","recid":"2000525","relation_version_is_last":true,"title":["押し込み「その場」ラマン分光と顕微光弾性解析による破壊直前のガラス構造の直接評価"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2024-08-20T05:36:47.603288+00:00"}
