Several ANSYS, Inc. publications, particularly the Mechanical APDL Verification Manual, describe additional
nonlinear analyses.
The Mechanical APDL Verification Manual consists of test case analyses demonstrating the analysis cap-
abilities of the program. While these test cases demonstrat e solutions to realistic analysis problems, the
Mechanical APDL Verification Manual does not present them as step-by-step examples with lengthy data
input instructions and printouts. However, most users who have at least limited finite element experience
should be able to fill in the missing details by reviewing each test case's finite element model and input
data with accompanying comments.
