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...

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...

Frankia strain CcI3 grown in culture produced a hemoglobin which had optical absorption bands typical of a hemoglobin and a molecular mass of 14.1 kDa. Its equilibrium oxygen binding constant was 274 nM, the oxygen dissociation rate constant was 56 s(-1), and the oxygen association rate constant was 206 microM(-1) s(-1).

The high strain rate compressive behaviour of a Silicone elastomer: Sylgard 184® is presented. Experiments were performed over strain rates between 3000 and 15,000 s -1 , and temperatures between -40 and +73 oC, corresponding to environmental conditions in many industrial applications. An Ogden strain energy density function was fit to the data, and the strain rate and temperature dependence of...

This study is focused on anomalous strain-rate-dependent behaviour of bacterial cellulose (BC) hydrogel that can be strain-rate insensitive, hardening, softening, or strain-rate insensitive in various ranges of strain rate. BC hydrogel consists of randomly distributed nanofibres and a large content of free water; thanks to its ideal biocompatibility, it is suitable for biomedical applications. ...

The viscoplastic behavior of high density polyethylene, polypropylene, and polycarbonate under uniaxial tensile loading at constant strain rate and large strains was studied. Standard ASTM samples of the polymers cast by injection molding were tested at room temperature and constant crosshead speed; testing was conducted in the range of 5 to 300 mm/min. A single constitutive relation which capt...
