The elastic limit of aluminium occurred at a stress of 4.7±0.2×10 8 Pa (46kg mm 2 ) and a strain of 1.27±.05%. At a total strain of 11.25% the stress was 11.7±0.2×10 8 Pa (115 kg mm 2 ).doi:10.1007/BF00561967W. H. Robinson...
The stress-strain behaviour of extruded AA6xxx and AA7xxx aluminium alloys in T6 temper was studied at a wide range of strain rates. Tensile tests at low to medium strain rates were performed in a standard tensile test machine, while a split-Hopkinson tension bar was used to carry out test...

The material is characterized by a nonlinear stress–strain curve which differs from that typically exhibited by hot-finished carbon steel, but shows similarities with other construction materials such as cold-worked steel and aluminium. Different material models describing this nonlinear stress–strain ...
Residual stress development in precipitation strengthened aluminium foundry alloys has seen little attention, despite the prevalence of their use over a wi
aluminiumstressstrainsThe 5XXX series of non-heat-treatable aluminium alloys, widely used in modern industry, have the peculiarity that an area near the welding bead, which reaches a temperature higher than 230掳C, suffers an annealing effect that causes a considerable decrease in yield strength. ...
Below, I show the results of the Plastic Strain data that I got. I try to input the plastic strain data to the Multilinear Kinematic Hardening Plasticity material model in Ansys. But, The graph shows this result, and there is an error notification before I start the simulation steps. I...
