WebThe Young's modulus of carbon and graphite artefacts. Measurements of dynamic Young's modulus have been made over the temperature range −196 to 1000°C on specimens of British nuclear-grade carbon heat treated at temperatures between 1200°C and 3000°C. The results are discussed in terms of the uniform stress model for graphite, … WebMar 28, 2013 · Based on the validation calculations in the case of graphite, we can estimate that the out-of-plane Young’s modulus of double layer graphene is about 2/3 of the out-of-plane Young’s modulus of graphite. Table 2. Out-of-plane Young’s modulus ( Ez) of double-layer graphene calculated under periodic boundary conditions.
