The corresponding element nodal force matrix is f Te = [ f 1 , f 2 ]e . We will place the element identifier “e” as either a subscript or superscript, but will always use the letter “e” for the purpose of identifying element-related quantities. The element and global nodal forces must be defined so that their scalar products with the corresponding nodal displacement increments gives an increment of work. 4. In most cases, meeting this requirement entails little beyond being careful to arrange the nodal displacements and nodal forces in the same order in the corresponding matrices.

11) will not change with time, so it needs to be computed only at the beginning of the calculation. 11) is called the consistent mass matrix. Semidiscrete Equations. e. the finite element equations for the model. At this point we will also consider the effect of the displacement boundary conditions. 14) The trial function then meets Eq. 5). For the test function to meet the conditions of Eq. 6), it is necessary that δu1 = 0 , so the nodal values of the test function are not arbitrary at node 1.

33): 〈A 0P〉 = 0. 4 Finite Element Discretization In Total Lagrangian Formulation Finite Element Approximations. The discrete equations for a finite element model are obtained from the principle of virtual work by using finite element interpolants for the test and trial functions. For the purpose of a finite element discretization, the interval [X a,X b] is subdivided into elements e=1 to ne with nN nodes. The nodes are denoted by X I, I = 1 to nN, and the nodes of a generic element by X eI , I = 1 to m, where m is the number of nodes per element.
