Products: ABAQUS/Standard ABAQUS/Explicit
The following features are tested in this verification problem:
Element-based distributed loading specified using the *DLOAD option.
Surface-based distributed loading specified using the *DSLOAD option.
Thermal loading specified using the *TEMPERATURE option.
In this verification test all the nodes of each element are fixed, and the reaction forces generated at the nodes as a result of the load application are used to verify the element load calculations. In addition, the effect of thermal loading applied using the *TEMPERATURE option is verified by allowing each element to deform freely in the thickness direction with the change in temperature. The resulting thermal strains in the thickness direction are compared with the analytical results.
Model:COH3D8 and COH3D6:
COH2D4:
COHAX4:
Initial conditions:
The calculated reactions are in agreement with the applied loads. In addition, the thermal stresses and strains in the thickness direction match the analytical results for the case of thermal loading.
