Boltzmann Superposition Principle

Creep under constant strain is not a practical way of evaluating a material performance. Boltzmann superposition principle explains the different stress loading profile to consider.

Material Behavior by Krish ChariApr 9, 20218:54 pmApril 10, 2021

Time-Temperature Superposition

This blog explains superposition principle, shift factor and Arrhenius, WLF equation. This principle is very useful to get creep compliance and stress relaxation curves for different test temperatures with reference temperature curves.

Material Behavior by Krish ChariApr 4, 202111:04 amApril 4, 2021

Creep Modulus

Creep modulus is an important design parameter for selecting plastics for long term use. This blog takes you step by step of the importance and curves to use for design purposes.

Polymer Deformation Mechanisms

This blog discusses crazing, shear yielding for amorphous polymers and slipping, twinning for semi-crystalline polymers. Deformation phenomenon explained thoroughly.

Material Behavior by Krish ChariMar 31, 20216:00 pmMarch 31, 2021

Yield Stress

Polymer yield stress depends on strain rate and temperature of the testing. This blog explains the both the factors and also Eyring’s model to predict the yield stress during polymer development.

Material Behavior by Krish ChariMar 27, 20211:48 pmMarch 27, 2021

Deformation mechanisms

Polymer deformation mechanisms helps to understand how amorphous and crystalline materials modulus can be predicted. A difficult topic but explained in layman terms.

Material Behavior by Krish ChariMar 21, 20219:26 pmMarch 21, 2021

Plastic Deformation

Here is the blog on various polymers behavior and stress/strain curves. Also covered topics are cold drawing, strain hardening and draw ratio of the polymers.

Material Behavior by Krish ChariMar 20, 202110:23 amMarch 20, 2021

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.
