| 内容記述 | Engineering plastics provide superior performance to ordinary plastics for wide range of the use. For polymer materials, dynamic stress and strain rate may be major factors to be considered when the strength is evaluated. Recently, high speed tensile test is being recognized as a standard testing method to confirm the strength under dynamic loads. In this study, therefore, high speed tensile test is analyzed by the finite element method; then, the maximum dynamic stress and strain rate are discussed with varying the tensile speed and maximum forced displacement. The maximum strain rate increases with increasing the tensile speed u/t but the strain rate concentration factor Ktέ(t) = έyA(t)/έynom(t) is found to be constant independent of tensile speed, which is defined as the maximum strain rate έyA,max appearing at the notch root over the average nominal strain rate at the minimum section έynom(t). It is found that the strain rate at the notch root έyA,max depends on the dynamic stress rate at the notch root σ yA,max and independent of the notch root radius ρ. It is found that the difference between the static and dynamic maximum stress concentration (σyA,max − σyA,st) at the notch root is proportional to the tensile speed when u/t ≤ 5000mm/s. Strain rate concentration factors are also discussed with varying the notch depth and specimen length. | |||||||||||||
