Three-layer fiberglass shell under thermomechanical action

The object of research is a section of a fiberglass pipe of a metallurgical enterprise's flue on sliding supports, working according to a split scheme. The material of the flue is fiberglass with mineral wool filler. The purpose of this work is to analyze the deflections of a three-layer cylindrical shell made of polymer composites under complex thermomechanical action and compare the results of full-scale and numerical experiments. The calculation considers the load from the own weight of the structure and the additional load. The range of gas operating temperatures from 22 to 130 °C is considered.
