Thermo-Elastic-Plastic Analysis of Plate Forming Process by Flame Bending Method

Flame bending process is one of the forming processes of steel plates. During this process, plate is formed with heating by gas torch flame followed by controlled cooling along specified paths. Considering simple tools used in the process, it is a popular and economical forming method. At present, this process is manually done on the basis of skilled technician’s experience. Experimental and ...

Combined Plastic Bending and Compression or Tension

So far we have assumed that a plastic hinge forms if the bending moment in a critical cross section reaches the plastic limit value, M0. We have tacitly neglected the effect of the other internal forces on the formation of the yield hinge. This effect, however, can be appreciable, for example in multi-storey frames or frames with a large horizontal thrust where the axial forces are large. So, w...

Geometrically Nonlinear Analysis of Plate Bending Problems

In the previous six chapters, we have discussed the application of T-elements to various linear problems. This approach can also be used to solve both geometrically [8-10,12] and materially [1,18] nonlinear problems. The former are treated in this chapter and the latter are addressed in Chapter 8. The first application of T-elements to nonlinear plate bending problems was by Qin [8], who presen...
