Several ANSYS, Inc. publications, particularly the Mechanical APDL Verification Manual and the Technology
Demonstration Guide, describe additional linear perturbation analysis examples.
The Mechanical APDL Verification Manual consists of test case analyses demonstrating the analysis cap-
abilities of the ANSYS family of products. While these test cases demonstrat e solutions to realistic ana-
lysis 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 some finite
element experience can infer the necessary details by reviewing each test case's finite element model
and input data with accompanying comments.
The Mechanical APDL Verification Manual includes the following linear perturbation analysis test cases:
