Explanation
The phenomenon that the strain of materials increases slowly with time while keeping the stress and temperature constant. Metals, macromolecule materials and rock all have creep properties under certain conditions. Different materials have different creep micromechanisms: the reasons for creep of polycrystalline materials are lattice slip caused by atomic intergranular dislocation and grain boundary diffusion; The creep mechanism of polymer is the change of indium structure and displacement of polymer molecule under the action of constant temperature and external force for a long time
