Influences of selected glass component additions on the shear modulus of a specific base glass.[7]
Shear modulus of copper as a function of temperature. The experimental data[8][9] are shown with colored symbols.

剪力模数（shear modulus）是材料力学中的名词，弹性材料承受剪应力时会产生剪应变，定义为剪应力与剪应变的比值。公式记为

G = \frac {\tau } {\gamma}

其中， G\, 表示剪力模数，\tau\, 表示剪应力，\gamma\, 表示剪应变。在均质且等向性的材料中：

G = {E \over {2(1 + \nu)}}

其中，E\, 是杨氏模数(Young's modulus )，\nu\, 是泊松比(Poisson's ratio)。

Shear strain
Influences of selected glass component additions on the shear modulus of a specific base glass.[7]
Shear modulus of copper as a function of temperature. The experimental data[8][9] are shown with colored symbols.

In materials science, shear modulus or modulus of rigidity, denoted by G, or sometimes S or μ, is defined as the ratio of shear stress to the shear strain:

where

Shear modulus' derived SI unit is the pascal (Pa), although it is usually expressed in gigapascals (GPa) or in thousands of pounds per square inch (ksi). Its dimensional form is MLT.
