Most of the verification tests in this section are based on the recommendations of the National Agency for Finite Element Methods and Standards (U.K.). The *RIGID BODY, ISOTHERMAL=NO and *RIGID BODY, ISOTHERMAL=YES options are tested in these problems.

The test problems are:

The one-element lumped model tests the *RIGID BODY, ISOTHERMAL=YES option. The simulation consists of two steps. In the first step the rigid body is cooled by convection from an initial temperature of =100 to the ambient temperature =20. In the second step the body is heated by a prescribed flux, q. All the thermal properties are equal to unity. In addition to its own thermal capacitance, a second capacitance is lumped into the model using a HEATCAP element.

The test is based on the one-element lumped model described in the previous section.

The tests are based on the problem presented in “T2: One-dimensional heat transfer with radiation,” Section 4.3.2 of the ABAQUS Benchmarks Manual. In the tests presented here, the *RADIATE option is replaced by equivalent nodal loads using the *CRADIATE option.

The tests are based on the one-element lumped model described earlier. The nodal thermal loads *CFILM and *CFLUX are used for cooling and heating the body, respectively. As with the *CRADIATE tests described earlier, in ABAQUS/Standard the nodal loads are weighted appropriately for the second-order elements; dummy mechanical and electrical properties are used for the coupled temperature-displacement and coupled thermal-electrical analyses, respectively.

The tests are based on the problems presented in “Thermal surface interaction,” Section 1.7.1, and “Coupled temperature-displacement analysis: one-dimensional gap conductance and radiation,” Section 1.6.3 of the ABAQUS Benchmarks Manual. In the first set of tests only the temperature variation in the rigid bodies involved in contact is considered, since the deformations are not of interest. In ABAQUS/Explicit two types of thermal contact are considered: thermal contact between a rigid body and an analytical rigid surface and thermal contact between two rigid bodies.

The second test is done in ABAQUS/Standard to test the friction dependency on field variables. The test is described in “Coupled temperature-displacement analysis: one-dimensional gap conductance and radiation,” Section 1.6.3 of the ABAQUS Benchmarks Manual; however, here we release the constraints in the tangential direction of contact.
