摘要：
The field dependence of the volume pinning force in anisotropic polycrystalline superconductors is calculated for various well established pinning models. The anisotropy substantially changes the field dependence of the volume pinning force and shifts its maximum to significantly lower reduced fields. A scaling procedure that allows the identification of the dominant pinning mechanism from the peak position is proposed.
