Jukka Aho e9ead51f24 test: Add comprehensive linear elastic material validation
- Tests LinearElastic material construction with parameter validation
- Validates Lamé parameter computation (λ and μ from E and ν)
- Stress computation tests: uniaxial extension, pure shear, hydrostatic pressure, general strain
- Verifies Hooke's law: σ = λ·tr(ε)·I + 2μ·ε
- Tangent modulus validation: 𝔻 = λ·I⊗I + 2μ·𝕀ˢʸᵐ (4th-order tensor)
- Double contraction consistency: σ = 𝔻 ⊡ ε
- Symmetry and isotropy property verification
- Tests both full and simplified compute_stress() interfaces
- Zero allocation and type stability checks
- 279 lines validating fundamental elasticity operations with Tensors.jl
