Abstract : The objective of this research effort was to determine whether the current finite element formulation in the SAMSON2 code for the eight-node quadrilateral higher-order isoparametric continuum element produces consistent and reliable results. Some effort was also performed toward investigating the finite element formulations for the five-node and the six-node triangular isoparametric continuum elements. Four tasks were executed in this research effort. The first task was a study of some of the previous work which had been performed. The second task involved comparisons between program results and analytical solutions for various problems. The third task was the verification and correction where necessary of the finite element formulation for the eight-node quadrilateral continuum element. The fourth task was a study of the effects on the problem results which were caused by the corrected finite element formulation.
