Expert-system-based rheology

Abstract

A rheometer is disclosed that includes rheometry logic that is responsive to a material selection control, to an objective selection control, to material property storage, and to process parameter storage, and is operative to assist the user with a measurement using the rheometer. In another general aspect, a rheometer includes sample history storage operative to store a history that spans a plurality of different operations performed by the rheometer on a same sample.

Description

[0001] Cross-references to related applications [0002] This application claims the benefit of US Provisional Application No. 61 / 137,640, filed August 1, 2008, which is incorporated herein by reference. technical field [0003] This application relates to rheometers, and applications of rheology. Background technique [0004] Rheology is the study of the flow and deformation of materials. An understanding of rheology can yield some critical insights for controlling and optimizing various industrial processes (eg, suction, extrusion, etc.) and consumer processes (shampoos, skin creams, etc.). [0005] Rheology is by its very nature a complex science. Accurate insights can often only be gained from properly set up experiments in which samples are loaded correctly, correct geometries are used, and accurate rheometry tests and test parameters represent process to request that insight. This is inherently difficult because, in addition to knowledge of the process, it requires...
