Considering the influence of compression stress, a critical criterion of adiabatic shear in orthogonal high speed cutting is given by linear perturbation on the compress-shear deformation continuum mechanics basic equations of the primary shear zone. Combining with the relationship of cutting conditions and deformation ones, also the materials constitutive relationship, a prediction model, which expressed...
A physical yet analytical phase change memory (PCM) model simultaneously accounting for thermal and electrical conductivities is presented. Due to the physics based nature of the model, the essential temperature from heating and cooling of PCM during operation is instantaneously updated. More importantly, the model can be applied to non-conventional circuit design technique. We show that for the first...
A theoretical model is proposed in this work for an evaluation of the specific heat and Debye temperature of thin-film semiconductors. In the model, the specific heat contributed by the confined acoustic phonons is calculated first. An effective Debye temperature is then defined by fitting the conventional Debye model to the calculated specific heat. It is found that the so-defined Debye temperatures...
