Abstract
The theoretical characterizations on the triangular‐form thixotropy loop tests of a LDPE melt (Q200) were performed in the present paper by using the simplified Mewis‐Denn model, which contains a modified upper convected Maxwell model and a kinetic equation. The simplified Mewis‐Denn model, containing five parameters, was obtained by reducing the multiple relaxation mode of Mewis‐Denn model to a single relaxation mode. The calculated results show that the simplified model can well describe the reported thixotropy loop experiments of the LDPE melt.
