 note = {高分子材料の強度は温度と速度によって変化し，特定の条件下で脆性破壊へと遷移する．特に応力集中がある場合には切欠き底で脆性破壊を起こす場合があり，その原因が切欠き底で高いひずみ速度が生じるためと考えられる.本研究では切欠き底でのひずみ速度と破断ひずみを整理し,時間-温度換算則が成立することを示す. Recently, high speed tensile test is being recognized as a standard testing method to confirm the strength under dynamic loads for engineering plastics. In our previous study, elastic strain rate concentrations are discussed by FEM. In this study, elastic-plastic FEM analysis is performed to confirm the real strain rate appearing at the notch root. Then, the master curve for the final fracture elongation for polycarbonate is constructed. It is found that the fracture behavior can be predicted for the wide range of impact speed under various temperatures from the master curve based on elastic-plastic analysis.},
