Z. Bazant, then a visiting associate research engineer at UC Berkeley, recalled: ……The founding of FEM waspaper in the ASCE Conf. on Electronic ComputationClough [14], which was the first to derive, by virtual work, the finite element stiffness matrix of an element of a continuum (a tr...
In the thin beam limit, the Timoshenko beam model must satisfy the Kirchhoff constraint γ=0 and the constraint κ=0. These constraints yield the trivial solution of the nodal displacements as wij=βij=0. In other words, the element locks. The lower-order basis functions cause an erroneous ...

By means of the element matrices, the matrices of the assembled system can be determined by sum, after the definition of a dummy matrix linking together the degrees of freedom qe of each element with the degrees of freedom qsof the whole system, i.e.: qe=Ceqs Therefore the potential and...
Figure 9.2.Beam-type finite element model; soil is modeled with nonlinear springs. Type of finite elements: The use of regular beam elements for the pipeline model is not recommended, because they cannot account for pressure. Instead, special-purpose “pipe elements” are preferable for pipelinese...
A method for solving space-time problems involving three-dimensional space wherein an unstructured four-dimensional finite element model is generated and solved to produce a four-dimensional solution. The four-dimensional mesh is generat... SR Kennon,SA Canann,SB Ward - US 被引量: 80发表: 2004...
A three dimensional finite element model (FEM) is introduced in this work in order to simulate the melt pool size during the Selective Laser Melting (SLM) process. The model adopts the Optical Penetration Depth (OPD) of laser beam into the powder bed and its dependency on the powder size ...
