Abstract
Two theoretical material models for nonlinear deformation of graphite due to Jones and Nelson are compared with Jortner's experimental results for uniaxial off-axis loading and biaxial loading of ATJ-S graphite specimens. The material models are extensions of the Jones weighted compliance matrix model and the Isabekian and Khachatryan restricted compliance matrix material model from linear to nonlinear deformation behavior. Both models include different behavior under tension loading than under compression loading.
