Abstract:The article addresses the modeling of the process of manufacturing a large-sized shell, given the thermomechanical behavior and viscoelasticity of the composite mandrel. The results of the experimental identification of viscoelasticity parameters of the examined material are presented. A numerical algorithm for adapting the experimental data for the ANSYS Mechanical APDL finite element analysis package is proposed. A Prony series expansion of the relaxation kernel is used as a model for describing the material… Show more
“…SME modelling can provide more accurate guidance for SMPs to serve in specified application scenarios. 14 Typically, constitutive models for polymers can be constructed to simulate their shape memory behaviour (e.g., thermoviscoelastic models [90][91][92][93][94] for cross-linked glassy SMPs analysis and the phase evolution models [95][96][97][98][99][100][101] for cross-linked semi-crystalline SMPs analysis). Constitutive models can be further integrated with the ANSYS to predict the shape change behaviour under different stimulus-response conditions.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
