Small Strain Behavior of Geomaterials: Modelling of Strain Rate Effects

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...

Effects of strain rate in laser forming

Experimental investigation and numerical simulation of the influence of the strain rate in laser forming are presented. To isolate and effectively study the strain rate effects, which are temperature dependent, a "constant peak temperature" method is developed with the aid of numerical modeling and solution. Under the condition of the constant peak temperature, the effects of strain rate on for...

Numerical Modelling of the Effects of High Strain Rate, Strain Path and Particles on the Formability of FCC Polycrystals

Significance of strain rate-dependence in modelling of organic materials

This paper explores the significance of the inherent strain rate-dependence of many biological materials. Such characteristics are pertinent to computational modelling of these materials for the purposes of surgical robotics and simulation. A pair of 2-dimensional fmite element models of the human brainlvenmcle system are developed and used to analyse the brain structural disease, hydrocephalus...

Static Strain Aging Behavior of Low Carbon Steel Drawn Wire

The static strain aging is a phenomenon that can change the mechanical properties of low carbon steels. Thus, the static strain aging behavior of low carbon steel wires after drawing process is studied. To do so, the wires are austenitized at different temperatures and cooled in different rates. Then the wires are drawn and aged at a specific temperature and time. Before and after aging of each...
