Axial direction is along the length of the beam or truss and not in either direction of the cross-section. mb. Ngo and Scordelis (1967) presented the first finite element analysis of reinforced concrete that included the effect of cracking. Why do FEA engineers use 1D elements ? Answer: There was no wrong answer to those questions, but one of the major advantages of 1D elements is that they allow to display directly the bending which is one of the root of failure in structures with long member structures. Each member of the truss has a solid circular cross section. iastate. This is a list of software packages that implement the finite element method for solving partial differential equations. These computer simulations work by taking larger, very complex geometry and breaks it up into thousands of tiny, simple parts that interact together (A good analogy of this is a Lego structure, where a complex object is actually comprised of many smaller, simple parts). Since a lot of civil engineering tools have come into the market, the engineers have a tendency to rely heavily on them which could be dangerous.
