For the improvement of car safety in collision, the development of high-speed processing technology, the refinement of practical constitutive equations for numerical simulation, and so forth, it is important to obtain accurate stress-strain relation of various materials in wide ranges of strain and strain rate. Through a series of numerical simulations of the specimen model of practical geometry by using the computer code LS-DYNA, some useful results in the determination of the geometry and dimensions of specimen suitable for dynamic tension test under the specified strain rate in the range 102-103 s-1, such as the effects of the rising time of input velocity and the lengths of grip and fillet on transient vibration, the relationship between the limits of gauge length and strain rate to give an adequate accuracy of dynamic stress-strain curves, and so forth, are obtained.
