DLOAD

User subroutine DLOAD can be used to define several types of nonuniform distributed loads. Examples of the use of this subroutine are shown in some of the tests described in other sections of this guide. The use of the subroutine is not limited to the applications shown in these tests. Pure bending of a cylinder: CAXA elements and Cylinder subjected to asymmetric pressure loads: CAXA elements illustrate the use of subroutine DLOAD to apply asymmetric loads to CAXA asymmetric-axisymmetric continuum elements. Refer to the problem description in Patch test for axisymmetric elements for an example of the use of the subroutine to define a nonuniform body force in the patch test for axisymmetric continuum stress-displacement elements. Subroutine DLOAD is also used in the test described in Nonuniform crack-face loading and J-integrals to apply uniform and nonuniform loads to a crack face.
