this paper investigates the earing phenomenon in deep drawing of aa3105 aluminum alloy, experimentally and numerically. earing defect is mainly attributed to the plastic anisotropy of sheet metal. in order to control such defect, predicting the evolution of ears in sheet metal forming analyses becomes indispensable. in this regard, the present study implements the advanced yield criterion bbc20...

Warm deep drawing of polypropylene, a semi-crystalline thermoplastic polymer, is studied using finite element analysis. In this process, circular polypropylene blank preheated to temperature much below its melting and drawn into the shape flat-bottom cylindrical cup punch-die combination, both initially at 25°C. The material model used for analysis considers effects varying strain rate during p...

Under the auspices of the DECOVALEX II international project, the coupled hydromechanical responses, in the fractured volcanic rocks at Sellafield site, to a pump test and shaft sinking were studied. The aim of this paper is to describe the methodology for analysing the hydromechanical responses of a long-term pump test in borehole RCF3 drilled on the centreline of one of the proposed shafts. T...
