AbstractIn this study, squeeze flow of viscoplastic cement-based extrudate has been investigated and a solution for the squeeze force as a function of the squeezing speed and other material parameters derived. The viscoplastic strain rates are obtained from the associated flow rule, which relates the strain rate to deviatoric stress through the coaxiality relation. For simplicity, the elastic response is neglected. The parameter study has shown that the upsetting process of cement-based extrudate can be predicted by the solution. The computed results have been used to compare with results of experiments conducted upon viscoplastic paste material. A reasonable agreement is observed. © 2007 ASCE.
