Small strain tensor

WebMar 8, 2024 · In the small strain condition, all the higher order terms in the Green strain tensor can be neglected. This yields Cauchy Strain Tensor , which is defined as, Here, the first 3 terms ε 11, ε 22, and ε 33 are engineering normal strains and ε 21, ε 23, and ε 13 are engineering shear strains. http://sml.me.cmu.edu/files/lectures/elasticity.pdf
