“…Nowadays, there is an expansion of polymer composites' applications in various industries, including construction. Polymer composites are very useful for making structures like chimneys, gas ducts, tanks, oil pipelines, and more [1][2][3][4][5][6][7][8]. This is possible because of the good combination of strength and weight, the resistance to aggressive substances, and the capability to adjust properties by changing the structure [9][10][11][12][13][14][15].…”

Developing a viscoelastic model for the cyclic thermomechanical loading of thermosetting polymers is the main goal of this study. The model includes memory for residual thermal stresses and can consider stress accumulation across many loading cycles. By considering stress accumulation, we can improve predictions and understand how thermosetting polymers’ stress–strain state changes under cyclic thermomechanical loading. This approach was validated through experimental verification to ensure its applicability in practical engineering scenarios. The experiment showed that the thermosetting polymer can accumulate stress during cycles of heating and mechanical loading during use. The results of the modeling and experiment are compared. The results have led to corrections in the way this model is applied to thermosetting polymers like the epoxy resin in this study. The corrected results matched well with the experimental measurements of stress under cyclic thermomechanical load, with a difference of only 1 to 6%.
