Plastic deformation of workpiece during unloading in plate compression
نویسندگان
چکیده
Deformation behaviour during loading and unloading is studied in compression of an aluminium plate with a high ratio between the diameter thickness by DLC coated die. A compressed becomes thinner after to larger reduction loading. The plastic deformation confirmed measuring increase unloading. optimum profile die crown approaches reverse shape elastic deflection flat at stroke end increasing thickness.

Plastic Deformation in Laser-induced Shock Compression of Monocrystalline Copper
Copper monocrystals were subjected to shock compression at pressures of 10-60 GPa by a short (3 ns initial) duration laser pulse. Transmission electron microscopy revealed features consistent with previous observations of shock-compressed copper, albeit at pulse durations in the us regime. The results suggest that the defect structure is generated at the shock front. A mechanism for dislocation...
متن کاملMeasurement of Superconducting Transition Curves of Lead during Plastic Deformation
The plastic enhancement effect is used as a new method for studying the transition curves of plastically deformed superconductors. Strainand temperature dependent field penetration below Hc is obser6ed. The phenomenon of enhanced plasticity in superconductors has been studied intensively in the last years /I/. In all experimental investigations of this effect the sample must be deformed alterna...
متن کاملRotations of brittle particles during plastic deformation of ductile alloys
Experimental evidence is presented to show that significant rotations of brittle phase inclusions of a Fe-rich intermetallic phase occur during plastic deformation on an Al Mg Si base wrought aluminum alloy. The particle rotations are quantitatively characterized, for uniaxial tension, compression, torsion, and notch-tension test specimens strained to different strain levels. The particle rotat...
متن کاملCharacterization of residual stresses generated during inhomogeneous plastic deformation
Residual stresses generated by macroscopic inhomogeneous plastic deformation are predicted by an explicit finite element (FE) technique. The numerical predictions are evaluated by characterizing the residual elastic strains by neutron diffraction using two different (hkl ) reflections. Intergranular residual elastic strains between subsets of grains are predicted numerically and verified by neu...
متن کاملReversible plastic events during oscillatory deformation of amorphous solids.
The effect of oscillatory shear strain on nonaffine rearrangements of individual particles in a three-dimensional binary glass is investigated using molecular dynamics simulations. The amorphous material is represented by the Kob-Andersen mixture at the temperature well below the glass transition. We find that during periodic shear deformation of the material, some particles undergo reversible ...
