When the load is removed, strain energy as: $U\; =\; \backslash frac\; 1\; 2\; V\; \backslash sigma\; \backslash epsilon\; =\; \backslash frac\; 1\; 2\; V\; E\; \backslash epsilon^2\; =\; \backslash frac\; 1\; 2\; \backslash frac\; V\; E\; \backslash sigma^2$ where σ is stress, ε is strain, V is volume, and E is Young's modulus: $E\; =\; \backslash frac\; \backslash sigma\; \backslash epsilon$ == Molecular Strain == In a molecule, strain energy is released when the constituent atoms are allowed to rearrange themselves in a chemical reaction interference are reduced.〔''March's Advanced Organic Chemistry: Reactions, Mechanisms, and Structure,'' Michael B. Smith & Jerry March, Wiley-Interscience, 5th edition, 2001, ISBN 0-471-58589-0〕 The external work done on an elastic member in causing it to distort from its unstressed state is transformed into strain energy which is a form of potential energy. The strain energy in the form of elastic deformation is mostly recoverable in the form of mechanical work. For example, the heat of combustion of cyclopropane (696 kJ/mol) is higher than that of propane (657 kJ/mol) for each additional CH2 unit. Compounds with unusually large strain energy include tetrahedranes, propellanes, cubanes, fenestranes and cyclophanes. 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「Strain energy」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.
