Strukova V.I., Kamenskikh A.A., Nosov Yu.O., Pustovalov D.O. Thermomechanical model of photopolymer material // Vestnik I. Yakovlev Chuvach State Pedagogical University. Series: Mechanics of a limit state . 2025. № 1(63). p. 65-75
Photopolymer resins after curing are the subject of research. The materials are widely used in additive manufacturing of prototypes for casting on burnt model. The negative impact of thermal expansion of photopolymer resins prototypes made, which leads to defects is noted by researchers. The aim of the work is to construct a viscoelastic model of the material. The mathematical description of the materials behavior is aimed at predicting the stress-strain state of the research object under complex technological conditions. The Maxwell model on the basis of Prony series, is chosen to describe the material behavior in the first approximation. The author’s numerical identification procedure is used to describe the material model. The Envisiontec SI500 behavior model construction was performed in the work based on data from experiments in the temperature range from 0 to 100 °C. The E(T,T˙) dependencies are constructed.
