Behavior of FRP Sandwich Panels under Synergistic Effects of Low Temperature and Cyclic Loading II: Results and Discussion

Abstract:

The companion paper presents experimental results and numerical simulation methods to illustrate the behavior of FRP sandwich panels under synergistic effects of low temperature and cyclic loading. This paper aims at verifying the proposed simulation methods and providing several examples of its application to FRP sandwich panels. In this regard, four categories were simulated including: perfect bonding, microcracks, debonding Case I, and debonding Case II. Each category contained six ABAQUS models with two types of loads, thermal loads and applied mechanical loads. Results showed that microcracking would lower the stiffness of the panel, but not as much as debonding between the core and the face sheets.
