Many patients with back pain, leg pain, or weakness of the lower extremity muscles are diagnosed with a herniated disc. When a disc herniation occurs, the cushion that sits between the spinal vertebra is pushed outside its normal position.

Another example is the right Cauchy-Green strain tensor (C_AB), which is symmetric (and geometrically is the pull back of the spatial metric by deformation mapping). If you linearize deformation gradient (F), you would not find a symmetric strain tensor. What is understood as linear strain is linearization of material strain tensor, which is one half C minus the material metric (E=1/2(C-G)). Because E is symmetric, its linearization will be symmetric too.
