During some of these processes, material is removed at atomic or molecular level specially in ion beam machining and elastic emission machining. In case of electron beam machining, material removal takes place due to thermal erosion. Here, the size of beam is so small that even a few micron size diameter holes can be drilled, thousands in numbers, in a few seconds. This process is suitable for μ-hole drilling in very thin electrically

Modelling of riveted joints in Finite Element Analysis (FEA) programs can be a complicated task. Previously beam elements have been used to represent fasteners where the shear stiffness of the beam has been approximated to that of the shear stiffness of the rivet. Errors result in this method since the beam can also support bending. Test results of rivets joining sheet metal components have shown that beams are not ideal at simulating a rivet in FEA. An acceptable method for simulating riveted joints in FEA

The reason for this is simply SolidWorks is not the best tool to use for complex designs and loads as ours was. It worked great for the simple beam deflection in the last project. Many times hand calculations are the long way of doing things. In this case, it took much longer to figure out the correct way of adding fixtures, load, and connections in SolidWorks.

Engineers consider some joints as pinned in their structural analysis, even though it is common knowledge that all joints exhibit some rotational constraint. For example beam-tocolumn joints made with a thin and non-extended end plate are actually semi-rigid but are modelled as frictionless pinned connections. Until recently there has been no reliable evidence that the idealisation of such joints is a safe building design

resistance of beams to bending. The deflection of a beam under load depends not only on the load, but also on the geometry of the beam's cross-section. This is why beams with higher area moments of inertia, such as I-beams are so often seen in building construction as opposed to other beams with the same cross sectional area. The higher the area moment of inertia, the greater the resistance to bending. The formulas for area moment of inertia for solid and hollow round beams are; Solid round beam (rod):

Nonlinear Nonlinear buckling analysis is more accurate than eigenvalue analysis because it employs non-linear, large-deflection; static analysis to predict buckling loads. Its mode of operation is very simple: it gradually increases the applied load until a load level is found whereby the structure becomes unstable (ie. suddenly a very small increase in the load will cause very large deflections). The true non-linear nature of this analysis thus permits the modeling of geometric imperfections, load perturbations
