The linear-elastic fracture toughness of a material is determined from the stress intensity factor ($K$) at which a thin crack in the material begins to grow. It is denoted KIc and has the units of $\backslash text\backslash sqrt\backslash sqrt$) which is directly proportional to $K\_^2/E$, where $E$ is the Young's modulus of the material. Note that, in SI units, $\backslash gamma\_$ is given in J/m2. ==Example values== The following table shows some typical values of fracture toughness for various materials: 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fracture toughness」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
