Abstract The modified analytic embedded atom method (MAEAM) model and the anharmonic theory are used to study the bulk modulus of fcc Al metal. The result shows that the bulk modulus can be described by a quadratic function of temperature. The result is in good agreement with the experimental data and theoretical results calculated by the first principle calculation etc. This outcome indicates that the temperature dependence of the bulk modulus for fcc Al metal can be academically studied with the MAEAM model combining with the anharmonic theory.
