WebFor these modules to have positive values, the Poisson’s ratio of a stable, isotropic, linear elastic material must be between −1.0 and +0.5. The value of Poisson’s ratio normally … WebTo obtain a sensible physical solution, replacing θby θ+ 2πshould give the same value of ∇Φ (see later). This is true only if Θ0(θ+2π) = Θ0(θ) ∀θ; i.e., either λ= 0 or cos2π √ λ= 1 and sin2π √ λ= 0 which implies 2π √ λ= 2nπfor some integer n.
