Reversed sequential test conditions to produce damage equivalent to the simultaneous exposure of polymeric materials to heat and radiation-construction of a computational program and numerical approach-

摘要

Numerical calculations of the degradation of polymeric insulations owing to thermal aging and radiation are performed to simulate reversed sequential acceleration tests. The aim is to identify testing conditions that produce material damage equivalent to the simultaneous exposure to radiation and heat. The paper also discusses trial calculations and the role of dose rate, radiation exposure time, temperature, and aging time.
