Viscoelastic Models – Intro
In this blog, you will learn about the how to model polymer behaviors with models. This is an intro to predict creep & stress relaxation behaviors.
Creep & Stress relaxation response diagrams
In continuation of “Four Regions of Viscoelastic Behavior”, this blog takes about the Creep and Stress Relaxation Response Diagrams in four mechanical states of polymer. Yes, It is very theoretical subject but important to know […]
Viscoelastic Equations
This blog is an intro to viscoelastic equations which are key for future blogs. Some of the equations are used to create viscoelastic models.
Four Regions of Viscoelastic behavior
This blog explains the four regions of polymer state under temperature or loading and how modulus changes in each state. Please watch other viscoelastic blog before watching this blog for better understanding.
