Forming limit curves (FLCs), which are constructed using the strains at localised necking, most widely used tools for evaluation of formability sheet metals. Fracture forming (FFLCs) more recently developed, complementary instead fracture. Since depends strongly on conditions such as strain state, temperature and rate, models predicting FLCs FFLCs essential optimisation further application hot ...

Hence it excludes proton decay and supersymmetry. The main predictions of a gauge model based on the exceptional simple Lie su-peralgebra mb(3|8) (a localized version of su(3) + su(2) + u(1)) are reviewed.

Low, intermediate and high strain rate tensile experiments are carried out on flat smooth, notched and central-hole tensile specimens extracted from advanced high strength steel sheets. A split Hopkinson pressure bar testing system is used in conjunction with a load inversion device to perform the high strain rate tension experiments. Selected surface strains, as well as local displacements, ar...

The necking instability is a precursor to tensile failure and rupture of materials. A quasistatically loaded free-standing uniaxial specimen typically exhibits at single location, thus corresponding long wavelength bifurcation mode. If confined substrate or embedded in matrix the same filament can exhibit periodic fragmentation creating segments finite length. While such instabilities have been...

purpose : primary localized amyloidosis of eyelid is a localized type of amyloidosis without evidence of systemic involvement, which is a quite rare clinical condition. here we report a case of primary localized amyloidosis of eyelid. case report : a 40-year-old woman presented with a four-month history of swelling of the left upper eyelid resulting in a mechanical ptosis. the mass had a firm b...
