Elastic-plastic finite-element analysis applied to metalforming allows the real macroscopic properties of the workpiece to be incorporated. This paper presents the results of an experimental study of the initiation of cracking in side-pressing of a heat-treated aluminium alloy (Duralloy 2014). Using an F. E. analysis, these are related to various fracture criteria. It is found that the criterio...

Five methods are introduced for design of castellated I beams encased in concrete. One of the methods, plastic analysis, is thoroughly explained and the relevant equations are developed. Eight castellated I beams encased in concrete are made and tested. The theoretical design methods are all compared with the test results and the safety factor for each method is calculated. The results show tha...

Plastic worm wheel is widely used in the vehicle manufacturing field because it is favorable for weight lightening, vibration and noise reduction, as well as corrosion resistance. However, it is very difficult for general plastics to secure the mechanical properties that are required for vehicle gears. If the plastic resin is reinforced by glass fiber in the fabrication process of plastic worm ...

In the present age of Sustainable development recycling of plastics is very much crucial and one good reason to recycle plastic is that there is just so much of it.. Plastic recycling happens to be one of the most advantageous ways for re-using plastic products. Another important cause remains hidden in the fact that plastics can take thousand of years to biodegrade. Therefore, analysis of barr...
