STRAIN-HARDENING AND RATE EFFECTS IN PLASTICITY
In this study the effects of strain-hardening and rate sensitivity in plasticity theory are investigated. Because the method of characteristics cannot be applied to problems involving rate dependent yield conditions (65) therefore a different procedure is developed. In this investigation of large …

Analysis of a bent constructed from a strain-hardening material
In conclusion, it can be said that the method of approach (whether by the minimum complementary energy or column analogy) is very straightforward, and the final set of equations can be developed very quickly. However, the final simultaneous solution presents a very difficult part of obtaining the …

A Detailed Investigation of the Strain Hardening Response of Aluminum Alloyed Hadfield Steel
The success of the model was tested by its application to different crystallographic orientations, and finally the polycrystals of the aluminum alloyed Hadfield steel. Meanwhile, the capability of the model to predict texture was also observed through the rotation of the loading axis in single …

On the role of lattice defects interactions on strain hardening: A study from discrete dislocation dynamics to crystal plasticity modelling
… slip-twin, and slip-precipitates interactions on strain hardening, with the intent of developing comprehensive modelling capabilities enabling to investigate unit processes and their collective effects up to the macroscopic response. To this end, the modelling strategy adopted in this work relies …

Constitutive modelling of the strain hardening behaviour of metastable AISI 301LN austenitic stainless steel as a function of strain and temperature
… of strength and ductility due to their high strain hardening abilities. Austenitic 301LN stainless steel is the least alloyed and most metastable among the 300-series austenitic stainless steels. Plastic deformation at a temperature below Md transforms the metastable austenite phase to a …
