3 Finite Element Types

3.1 Used finite element types

3.1.1 The structural assessment is to be based on linear finite element analysis of three dimensional structural models. The general types of finite elements to be used in the finite element analysis are given in Table 1.

Table 1 : Types of finite element

Type of finite element Description
Rod (or truss) element Line element with axial stiffness only and constant cross sectional area along the length of the element.
Beam element Line element with axial, torsional and bi-directional shear and bending stiffness and with constant properties along the length of the element.
Shell (or plate) element Shell element with in-plane stiffness and out-of-plane bending stiffness with constant thickness.

3.1.2 Two node line elements and four node shell elements are, in general, considered sufficient for the representation of the hull structure. The mesh requirements given in this chapter are based on the assumption that these elements are used in the finite element models. However, higher order elements may also be used
