Problem description

Material:

Linear elastic, Young's modulus = 210 GPa, Poisson's ratio = 0.0.

Boundary conditions:

= 0 at point B.

Loading:

A concentrated moment at point A applied in increments up to a maximum value of

Reference solution

This is a test recommended by the National Agency for Finite Element Methods and Standards (U.K.): Test NL5 from NAFEMS Publication NNB, Rev. 1, “NAFEMS Non-Linear Benchmarks,” October 1989.
