The Lame's First Parameter (E,G) calculator computes Lame's parameter based on the Shear Modulus and Young's Modulus.
INSTRUCTIONS: Choose units and enter the following:
Lame's First Parameter (E,G) (λ): The parameter is returned in Newtons per square meter (N/m2). However, these can be automatically converted to compatible units via the pull-down menu.
The Lame's First Parameter, `lambda`, is used in the equation computing the stress in 3D satisfying Hooke's Law. This equation defines Lame's First Parameter in terms of the Young's Modulus (E) and the Shear Modulus (G).
`lambda = G * (E - 2*G) / (3*G - E)`
