Structural user element
Elements tested
User element.
Features tested
Accessing various Abaqus materials from a user element material point.
Problem description
The finite element model for each test case consists of a single 4-node user element subjected to uniaxial deformation. The element corresponds to Abaqus element CPE4. Different Abaqus materials are accessed from user subroutine UELMAT in each test.
Results and discussion
The results agree with the results obtained using an identical model with Abaqus element CPE4 instead of the user element.
