A model for experimentally-observed high-strain-rate dynamic strain aging in titanium

High Strain Ra 33 . High Strain Rate and Impact Experiments

Experimental techniques for high-strain-rate measurements and for the study of impactrelated problems are described. An approach to classifying these experimental techniques is presented, and the state-of-the-art is briefly described. An in-depth description of the basis for high-strain-rate experiments is presented, with an emphasis on the development of a range of strain rates and a range of ...

The Prediction of Dynamic Strain in Ring Type Compressor Valves Using Experimentally Determined Strain Modes

A Strain Range Dependent Cyclic Plasticity Model

Hysteresis loop curves are highly important for numerical simulations of materials deformation under cyclic loadings. The models mainly take account of only the tensile half of the stabilized cycle in hysteresis loop for identification of the constants which don’t vary with accumulation of plastic strain and strain range of the hysteresis loop. This approach may be quite erroneous particularly ...

Mechanical Behavior of TWIP Steel in High Strain Rate Torsional Test

Advanced high strength steels (AHSS) have recently attracted great attention because of their superior mechanical properties. A modern group of these steels, known as twinning induced plasticity (TWIP) steels, shows a unique combination of strength and ductility even at high rates of strain. In order to examine the functionality of such steels in dynamic loading conditions, their mechanical beh...
