概要
- 論文の詳細を見る
The mechanical properties of PMMA were assumed to be reproduced from a three-parameter solid type of mathematical model consisting a spring in parallel with a Maxwell element. The longitudinal strain variations were measured at two different locations in a bar of PMMA. The measured strain at one locations was approximately resolved into strains with ramp distributions in time. The analytical solution based on the one dimensional theory of longitudinal impact was obtained for the strain of the other location by superposing the ramp responses. The dynamical three parameters at different stages of iteration were given. convergence of iteration was satisfactory.
