Strain Rate Dependence of Stress-Strain Curves in a Ti-Fe-O Alloy.

Strain glass transition in a multifunctional β-type Ti alloy

Recently, a class of multifunctional Ti alloys called GUM metals attracts tremendous attentions for their superior mechanical behaviors (high strength, high ductility and superelasticity) and novel physical properties (Invar effect, Elinvar effect and low modulus). The Invar and Elinvar effects are known to originate from structural or magnetic transitions, but none of these transitions were fo...

A New Technique based on Strain Energy for Correction of Stress-strain Curve

Tensile stress-strain curve is of high importance in mechanics of materials particularly in numerical simulations of material deformations. The curve is usually obtained by experiment but is limited by necking phenomenon. Engineering stress-strain curve is converted to true stress-strain curve through simple formulas. The conversion, however, is correct up the point of necking. From this point ...

The Dependence of Isothermal ω Precipitation on the Quenching Rate in a Metastable β-Ti Alloy

The precipitation behavior of the α strengthening phase in metastable β-Ti alloys is highly dependent on heat treatment parameters such as quenching rate, heating rate and ageing temperature. In this paper we have investigated the influence of quenching rate on the formation of isothermal ω precipitates that have been regarded as potent nucleant sites for α precipitation. The results show that ...

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...
