ANSYS Simulation of the Thermomechanical Behavior of a Large-Sized Composite Mandrel with Consideration of Viscoelasticity

The article addresses the modeling of process manufacturing a large-sized shell, given thermomechanical behavior and viscoelasticity composite mandrel. results experimental identification parameters examined material are presented. A numerical algorithm for adapting data ANSYS Mechanical APDL finite element analysis package is proposed. Prony series expansion relaxation kernel used as model describing behavior. effect temperature on rate processes taken into account through application temperature-time analogy according to Williams–Landel–Ferry formula. selected with calculated was implanted commercial APDL. Simulation two steps product performed: winding heat treatment shell. For this purpose, quasistatic problem mechanics unsteady thermal conduction under conditions convective transfer were solved by method. influence mandrel normal pressure acting surface function force factors estimated quantitatively qualitatively. It found that respect nonlinear material, level decreases 50% compared case using models elastic This result justifies importance complex in studying long-term technological processes, especially those associated high-temperature effects.
