Elasticity tensor is perfectly valid for non-linear materials

Latest comment: 2 years ago1 comment1 person in discussion

The first sentence is misleading. The elasticity tensor can be defined as the second derivative of the stored energy function with respect to strain. This quantity is well defined for any twice differentiable stored/free energy function. It need not be quadratic in strain, i.e. the material need not be linear elastic. 2A00:20:C060:B9DE:CD1F:EF1F:7A43:2AE7 (talk) 06:27, 24 May 2023 (UTC)Reply

Tensor for fluids

Tensors for various special cases of solids are described, but it would also be handy to mention the tensor form for a fluid. 162.246.139.210 (talk) 20:15, 17 June 2025 (UTC)Reply
