| 内容記述 | Generally, measurements of the stress-strain curve are required in order to determine the yield strength. However, it is difficult to measure dynamic stresses induced in materials due to the complicated propagation of the stress waves. In contrast to this, measuring strain data is relatively easy. When the materials are subjected to impact force, elastic waves propagate first. After the strain becomes larger than yield strain, plastic waves occur. Therefore the strain rate changes discontinuously at this point, although the strain increases smoothly. By measuring the strain waves induced in a test piece rod subjected to longitudinal impact force as a step waveform, the strain rate profiles are obtained based on numerical differentiation. For the previous reason, the dynamic yield point can be estimated by change of the strain rate. The dynamic yield stresses are obtained by multiplying those values by Young's modulus measured from the static compress or tensile tests. This paper confirmed the possibility of the present method based on numerical simulations and discussed practicality by measuring the dynamic yield strength of materials under various strain rates. | |||||||||||
