… In an isotropic elastic body, Young's modulus, rigidity modulus, bulk modulus, and Poisson's ratio are not independent, but are interrelated. As mentioned above, there are two independent elastic coefficients in an isotropic elastic body, and the two that are often used are the Lamé elastic coefficients (also called Lamé constants) λ and μ, introduced by the Frenchman Gabriel Lamé (1795-1870). When these are used, the following relationship holds. [Ninomiya Toshiyuki] … *Some of the terminology that mentions "Lamé, G." is listed below.

… 等方性弾性体ではヤング率,剛性率,体積弾性率,ポアソン比は独立ではなく,相互に関係づけられる。前述のように,等方性弾性体で独立な弾性係数は2個であり,その2個としてよく用いられるものに,フランスのラメGabriel Lamé(1795‐1870)によって導入されたラメの弾性係数(ラメの定数ともいう)λ,μがあるが,これを用いると,の関係がある。【二宮 敏行】。… ※「Lamé,G.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
