商品描述

This book bridges the gap between theoretical rheology and practical industry applications by introducing Control Theory (CT) and the linear Unified Model. This approach enables the modelling and analysis of various viscoelastic flows as well as polymer and macromolecular structures. In practical engineering, the design of machinery and equipment for polymers often relies on handbooks, respective textbooks, and numerous CAD-aided software tools based on empirical formulas. This book presents many useful viscoelastic constitutive equations for analysing and model shear and complex flows, relaxation modulus and spectrum, elongation, transient viscosity, and for computing the Molecular Weight Distribution (MWD) from viscoelastic measurements.

The book adopts a counterintuitive approach, starting afresh and proceeding chronologically from steady-state viscosity and other flows relevant to practical engineering to the theoretical formulas of relaxation phenomena. It simplifies unnecessary complexity while still drawing on the well-documented motions of molecular chains. Furthermore, the book offers deeper insights into the background of power-law theories and the Cox-Merz rule, supplying new formulas for the relaxation modulus, spectrum, and various modules through the application of unified formulas. Professionals and scholars alike will find it a handy reference tool.

商品描述(中文翻譯)

這本書彌補了理論流變學與實際工業應用之間的差距，通過介紹控制理論（Control Theory, CT）和線性統一模型來實現。這種方法使得各種粘彈性流動以及聚合物和大分子結構的建模和分析成為可能。在實際工程中，聚合物的機械和設備設計通常依賴於手冊、相關教科書以及基於經驗公式的眾多CAD輔助軟體工具。本書提供了許多有用的粘彈性本構方程，用於分析和建模剪切流和複雜流動、鬆弛模量和光譜、延伸、瞬態粘度，以及從粘彈性測量中計算分子量分佈（Molecular Weight Distribution, MWD）。

本書採用了一種反直覺的方法，從穩態粘度和其他與實際工程相關的流動開始，按時間順序進行，最終到達鬆弛現象的理論公式。它簡化了不必要的複雜性，同時仍然依賴於分子鏈的運動的良好文獻記錄。此外，本書深入探討了冪律理論和Cox-Merz法則的背景，通過應用統一公式提供了鬆弛模量、光譜和各種模量的新公式。專業人士和學者都會發現這是一本方便的參考工具。

作者簡介

Tommi Borg has been active in plastics conversion since the 1960s, starting as a trainee at extrusion and polymerization plants in Finland and Sweden. He studied physics and computer science at the University of Oulu during the 1970s, leading to his first Finnish patent being granted in 1977, followed by his first international patent in 1989. He has decades of experience in engineering extrusion lines and die designs. He worked at extrusion plants from 1979 to 1993, after which he became an independent researcher and an international consultant in plastics and software. He focused on developing viscoelasticity models that were more accurate than existing Maxwell and power-law models.

作者簡介(中文翻譯)

Tommi Borg 自1960年代以來一直活躍於塑料轉換領域，最初在芬蘭和瑞典的擠出及聚合工廠擔任實習生。他在1970年代於奧盧大學學習物理和計算機科學，並於1977年獲得第一項芬蘭專利，隨後在1989年獲得第一項國際專利。他在工程擠出線和模具設計方面擁有數十年的經驗。他於1979年至1993年在擠出工廠工作，之後成為獨立研究員及塑料和軟體的國際顧問。他專注於開發比現有的Maxwell和冪律模型更準確的粘彈性模型。
