Linear form

These notes are part of my notes on linear algebra.  I believe that textbooks of linear algebra give a bad definition of linear form.  The last section of the notes explain why it is bad.  I also give examples of linear form everyday life and from physics.  Given the vector space of distance, both force and electric field are dual spaces of the space of distance.  They are distict dual spaces of the space of distance, and they are not dual spaces to each other.

Finite Eigenstrains in Nonlinear Elastic Wedges

Eigenstrains are created as a result of anelastic effects such as defects, temperature changes, bulk growth, etc., and strongly affect the overall response of solids. In this paper, we study the residual stress and deformation fields of an incompressible, isotropic, infinite wedge due to a circumferentially-symmetric distribution of finite eigenstrains. In particular, we establish explicit exact solutions for the residual stresses and deformation of a neo-Hookean wedge containing a symmetric inclusion with finite radial and circumferential eigenstrains.

"Evaluation of stresses in Isogeometric analysis"


I am trying to find the method of stress evaluation used in Isogeometric analysis. I havn't come to know any numerical process for stress computation along with its implementation in IGA.  Can someone please help me in this regard.

Thanks -Vishal

Evolution of elastic modulus in roll forming

Abstract: Roll forming is a continuous process in which a flat strip is incrementally bent to a desired profile. This process is increasingly used in automotive industry to form High Strength Steel (HSS) and Advanced High Strength Steel (AHSS) for structural components. Because of the large variety of applications of roll forming in the industry, Finite Element Analysis (FEA) is increasingly employed for roll forming process design. Formability and springback are two major concerns in the roll forming AHSS materials.

Effect of extension twins on texture evolution at elevated temperature deformation accompanied by dynamic recrystallization

 High temperature deformation processing of magnesium and its alloys is often 
accompanied by dynamic recrystallization (DRX). Deformation twinning is one of the main 
deformation mechanisms in HCP metals, but very few works are available in literature 
(experimental or modelling) which investigate the effect of the deformation twinning on 
dynamic recrystallization. The current study provides insights regarding the deformation

Reconstruction of the 3D representative volume element from the generalized two-point correlation function

This paper presents the first application of three-dimensional (3D) cross-correlation 
microstructure reconstruction implemented for a representative volume element (RVE) to 
facilitate the microstructure engineering of materials. This has been accomplished by 
developing a new methodology for reconstructing 3D microstructure using experimental two-
dimensional electron backscatter diffraction data. 

Summer School - HPC for Engineering Simulation

The STFC Hartree Centre (in Warrington, UK - located between Manchester & Liverpool) is running 4 high performance computing summer schools from June to July 2016. They are primarily aimed at PhD students and postdoctoral researchers, but are also open to academics and industry at no extra cost. The tuition fees are subsidised by STFC and each week only costs £150. There is a 1 week school on each of the following topics:

Post-doctoral position in Computational Materials Mechanics at NUS, Singapore

We have an opening for a post-doctoral fellow position in multiscale computational mechanics of polymers. The project focuses on modeling and simulation of the thermo-mechanical behavior of polymers with covalent adaptable networks (CANs), e.g. vitrimers. The objective is to formulate a hierarchical modeling and simulation approach, which closely mimics key steps in the recycling and reshaping processes of CAN polymers by embedding the physics at two length-scales – (i) discrete-continuum (meso-scale) and (ii) homogenized continuum (macro-scale).

Secret of high strength and toughness of abalone seashell

Among all inspiring bio-material, Abalone seashell has its unique characteristics of high strength and toughness. Though , there is the general trend in materials that some of the toughness have been compromised for the sake of increasing hardness and vice versa. This astonishing property of sea shell attracts material scientists to understand the root cause for this property. One of such enthusiast, Prof. Kalpana Katti at North Dakota State University unlocked these secret of these phenomenon lies in its microstructure.
