The invention discloses a material-data processing method, a material-data generating method, a material-data application method and terminal and a material-data cloud processing platform. The material-data processing method includes the steps that the material simulation request from a user terminal is received, and the material simulation request comprises material experiment request information of the user terminal; the material experiment request information is subjected to material experiment simulation through a preset simulation tool to generate simulation material data; the simulation material data is sent to the user terminal, wherein the simulation material data is sued for indicating the user terminal to carry out an authentic material experiment. By means of the material-data processing method, the technical problem that a material experiment and material simulation calculation are disjointed in the existing material genetic engineering technology is solved, the actual experiment problem can be solved through the simulation material data accordingly, and new-material research and development are quickened.
