Computing flow-induced stresses of injection molding based on the Phan–Thien–Tanner model
A numerical approach is introduced to solve the viscoelastic flow problem of filling and post-filling in injection molding. The governing equations are in terms of compressible, non-isothermal fluid, and the c...
