Internal Pressure Measurement for Thick Wall Cylinder In Impact Fatigue Test
带内裂纹厚壁圆筒管冲击疲劳实验中内压测定技术

A circulating loading experimental apparatus is designed. The apparatus is used to produce impact internal pressure for the thick wall cylinder in fatigue test. By measuring the dynamic strain of the cylinder and calculating the dynamic strain by finite element method, the impact internal pressure of experiment is determined.
