Application of User Subroutine UAMP of ABAQUS

When we put a nolinear force that is the function of time、velocity or displacement on a part of a model,it is hard to realize that to use the amplitude of the force. However,the user subroutine UAMP or DLOAD of ABAQUS can realize that function easily. This article described the function of UAMP and studied the use of UAMP. Because of this,user subroutine of ABAQUS is efficient in dealing this kind of problem.
