Advanced high-strength steel (AHSS) is a highly competitive material for the automobile industry to resolve challenge of weight reduction and passenger safety. Cold hot composite roll forming newly developed manufacturing technology, which aims overcome defects such as microcrack, severe work hardening, thickness reduction, large corner radius in traditional cold process AHSS. In this paper, ma...

A standard test field containing numerous strong sources has been observed twice with the ASKAP BETA system, with the third axis of motion – the roll axis – disabled for the second run. These two data sets are subjected to identical calibration and imaging pipelines in order to gauge the e↵ects of the roll axis when observing with a Phased Array Feed. Present beam forming techniques only allow ...

Abstract Bistable metal sheets with a coiled transport geometry and an unfolded profile as second stable state, are of great interest lightweight components. It is well known that specific distribution residual stresses necessary to enable bistable properties. With the help numerical FE models, optimal process parameters for production such evaluated. Afterwards, incremental bending roll formin...

determination of the deformation length is one of the first steps in roll forming design. roll forming industries are very interested in explicit simple relationsfor prediction the deformation length without using trail-and-error methods at workshop or time consuming finite element simulations. in this paper, elastic properties and work-hardening behaviour of the strip are considered in additio...
