Effect of rounding error on the accuracy of structural analysis

[摘要] In order to estimate accuracy of structural analyses, the authors introduce a systemic set of examples with analytic solutions that can be presented, through the finite element method, in form of whole numbers and fractions. The three-cube Lagrange elemen
