WebApr 12, 2013 · Beam elements have played a very important role in modeling mechanical engineering structures. Curved beams are known to be more efficient in transfer of loads than straight beams. The transfer in the curved beam is affected by means of bending, shear and membrane action. This is particularly important in studying initially curved … Webcurved beam is, in fact, a 2D or 3D entity although we will model it as being 1D. The first order theory we are in the process of deriving is a 1D theory based solely on the deformation of the neutral bending axis. An important argument of W.T. Koiter that carries over to shell theory is that for a first order curved beam or plate theory (i.e. a
