Automated sorting for plastic recyclables has been seen as the way forward in the plastic recycling industry. Automated sorting provides significant improvements in terms of efficiency and consistency in the sorting process. In the case of macro sorting, which is the most common type of automated sorting, efficiency is determined by the mechanical details of the material handling system as well...

Laysan albatross (Phoebastria immutabilis) ingest plastic marine debris of a wide range of shape, sizes and sources. To better characterize this plastic and provide insights regarding its provenance and persistence in the environment, we developed a simple method to classify plastic fragments of unknown origin according to the resin codes used by the Society of Plastics Industry. Known plastics...

With the rapid and sharp rise in energy prices in Jordan, energy cost is becoming a value that cannot be ignored in the Jordan’s industrial sector. However, there are still many practices adopted in industry that do not take energy efficiency as a prime consideration, but rather focus on immediate and direct savings in materials and machinery. This study examines potential opportunities of elec...

Sandwich construction is widely accepted as a method of construction especially in the aircraft industry. It is a type of stressed skin construction formed by bonding two thin faces to a thick core, the faces resist all of the applied edge loads and provide all or nearly all of the required rigidities, the core spaces the faces to increase cross section moment of inertia about common neutral ax...

The springback phenomenon that occur in thin metal sheets after forming is mainly a stress driven problem, and the magnitude is roughly proportional to the ratio between the magnitude of the residual stresses after forming and Young’s modulus. An accurate prediction of residual stresses puts, however, high demands on the material modeling. A phenomenological plasticity model is made up of sever...

Abstract Vacuum-forming is a common manufacturing technique for constructing thin plastic shell products by pressing heated sheets onto mold using atmospheric pressure. ubiquitous in packaging and casing the industry, spanning fast moving consumer goods to connected devices. Integrating advanced functionality, which may include sensing, computation communication, within structures desirable var...
