Analysis on Nonlinear Stress-Growth Data for Shear Flow of Starch Material with Shear Process

Abstract EN

The material function of liquid materials for packaging plays an important role in analysis of its mechanical behavior.

The mechanical behavior of material affects the packaging process in many aspects, such as selection of packaging materials and preparation of packaging method.

Therefore, research on the material function of the liquid material is very helpful to guide the packaging process and look into how the packaging quality and efficiency are affected by the mechanical properties of material.

This paper established the material function for the starch solution under shear process.

With the relaxation test of the starch solution specimens, the G(t) function and dumping function were established and verified.

Based on the memory function of starch solution, the material function of starch solution was constructed and approved to be efficiently predict the mechanical behavior during the shear process.

Therefore, such material function can be used to guide the operation on the shear flow.
