Abstract Discretising a structure into elements is a key step in finite element (FE)
analysis. The discretised geometry used to formulate an FE model can greatly affect
accuracy and validity. This paper presents a unified dimensionless parameter to generate
a mesh of cubic FEs for the analysis of very long beams resting on an elastic foundation.
A uniform beam resting on elastic foundation with various values of flexural stiffness and
elastic supporting coefficients subject to static load and moving load is used to illustrate
the application of the proposed parameter. The numerical results show that (a) Even if the
values of… More >
