Abstract |
|
内容記述 |
A practical model of a temperature and strain-rate dependent dynamic constitutive equation for carbon steels is proposed. Unknown material constants involved in the proposed constitutive equation can be determined by the non-linear least squares method, which approximates ordinary-impact-test results with calculated values of elasto-plastic waves propagation analyses. In addition static stress-strain curves, longitudinal elastic modulus and yield stress, which are needed for elasto-plastic waves propagation analyses with the proposed constitutive equation, are expressed as a function of temperature. These results enable elasto-plastic waves propagation analyses under wide strain-rate and temperature ranges easily. The present paper has actually determined material constants involved in the proposed constitutive equation and compared the calculated results with measured ones. As a result, it has been confirmed that the proposed equation is applicable at a wide strain rate range and at a room temperature to less than one in which blue brittleness occurs. |
