Abstract
An automatic method of yield line analysis, due to Munro
and Da Fonseca, involves the use of an arbitrary
finite-element mesh. This paper discusses the problem of
optimizing the mesh in order to bring its edges more
closely into alignment with the true yield lines, thus
improving the accuracy of the prediction of collapse load.
