Scalar done wrong
Update on 9 April 2016. At the bottom of this post, I attach a pdf file of my notes on scalar.
Notes on scalars now forms part of my notes on linear algebra.

Hello
I'm working on a project & I'm in a trouble. I need to know creep relations for a porous material under undrained condition and constant stress. I'll be gratefull if you help me.

I attach some class notes developed by the late Professor Donald Carlson from which many generations of students at the University of Illinois learnt Continuum Mechanics.
Textbook on linear algebra
Linear algebra is significant to many aspects of mechanics. For some years I have been using the book by Shilov. But this book may or may not be a good one to recommend to a student, depending on his or her prior experience. On StackExchange Mathematics, there are several excellent threads discussing textbooks of linear algebra. A particular recommendation was made for
Residual stresses 2D to 3D

Hello,
i have simulated welding in 2D model for beam attached with cover plates at both the flanges using Abaqus, now i want to use the same residual stress distribution for whole 3D cover plated beam with same cross-section,so that i can find load carring capacity of beam.
but i am not sure, is it possible to find stresses in 2D model then use the same residual stress in 3D model? i try using initial state and restart option but it is not reading the same stresses for whole lenght.so is there any other way of doing this??
Mismatch between built-in linear-elastic material behaviour and tutorial VUMAT in ABQ/Explicit using truss elements

Hello dear all,
for my master's thesis I'd like to write a simple VUMAT for a material with nearly zero compression stiffness.
So for a better understanding of VUMAT subroutines I did the ABQ tutorial for a VUMAT with isotropic, isothermal elastic material behaviour and compared the results with the built-in material definition.
There is a discrepancy of almost 35% of the S11 stress. ABQ Manual says that both times the Green-Naghdi stress-rate formulation is used.
