Numerical analysis of beam and surface structures under large displacement
Space 3D structures consisting of the beam and the surface elements are often encountered in the engineering practice. Here is presented the three-dimensional state of the mentioned structures as a combination of beam and shell states. Both finite elements, two nodes rectilinear FE and four nodes superparametric shell FE, have six DOF per node. The tangent method is used in the null configuration approach of load and internal forces updating. Updating the large translation displacements in the incremental procedure follows from simple summarizing of their vectors from the increment to increment. Updating the large rotations is simplified to rotations of the rigid body. This assumption will be acceptable if the FE is sufficiently small and the internal forces and hence the stresses within FE are expressed within small displacement of each increment.
