For coupled temperature-displacement elements dummy thermal properties are prescribed to complete the material definition. Boundary conditions:. Step 1A distributed pressure loading of 1000/area is applied on each face.
For lower-order elements the test description is complete. For higher-order elements, another step definition is included. Step 2Hydrostatic pressure loading is applied along the two vertical faces, varying from 0 at the top to 1000/area at the bottom, in addition to the loads of Step 1. The following reference solution is obtained for Step 2 using CAXA84 axisymmetric solid elements with nonlinear, asymmetric deformation (input file eref84s3.inp) and is given at 0.5.
Results and discussionElements using reduced integration may have additional boundary conditions to those specified above. All elements yield exact solutions. Section output requests to the results (.fil) file and to the data (.dat) file are used in some of the input files to output accumulated quantities on the face CD. The quantities are reported in a system that is local to the section. Input files
