TīmeklisThere are only two independent parameters in the general Hooke’s law. However, a special material constant named the shear modulus, G, which is related to E and n, defines the relationship between shear stresses and shear strains: ... ij is the unit matrix and l and µ are the Lame parameters: In continuum mechanics, Lamé parameters (also called the Lamé coefficients, Lamé constants or Lamé moduli) are two material-dependent quantities denoted by λ and μ that arise in strain-stress relationships. In general, λ and μ are individually referred to as Lamé's first parameter and Lamé's second … Skatīt vairāk • Elasticity tensor Skatīt vairāk • K. Feng, Z.-C.

Tīmeklis2015. gada 1. janv. · The values of the material parameters for several materials are given in Table 1.1 (Reddy 2003). T is the transformation matrix which represents the relation of the principal material coordinate system (1, 2, 3) of the k th layer with respect to the shell coordinate system ( α , β , z ). TīmeklisThe parameters μ and λ are the Lamé parameters from linear elasticity. This model reduces to the isotropic linear elastic model for small strains and rotations. The Cauchy stress is given by, (2) σ = μ J ( b − I) + λ J ( ln J) I, and the spatial elasticity tensor is given by. (3) C = λ J I ⊗ I + 2 J ( μ − λ ln J) I ⊗ _ ¯ I.
