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.

Hi,

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

Job Description & Specifications:

The School of Civil and Environmental Engineering, Nanyang Technological University is seeking for a potential candidate for research positions as Project Officer or Research Associate.

The PO/RA will work on a project to conduct the research on real-time geotechnical monitoring using fiber optic sensors.

The roles of this position includes:

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.

Spend a week at MIT and earn a MIT certificate. A great opportunity for postdocs and graduate students. Limited number of fellowships available. 

June 20-24, 2016

Two PhD positions are available immediately in Computational Mechanics & Materials.

One project (NSF grant) is about multi-phase field modeling of formation and evolution of intermetallics and oxides at high temperatures in advanced high strength steels. Another project (NSF grant) is about multi-phase field modeling of evolution of oxide bifilms in solidification of metals. 

The nonlinear dynamics laboratory at the University of Rhode Island has an open position for a PhD student supported through research assistantship (including tuition remittance) starting Summer or Fall 2016. This position is supported by NSF grant. This research has a multidisciplinary nature incorporating material science, dynamical systems modeling, fatigue testing, and nonlinear time series analysis.

 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 
mechanisms of magnesium alloy during compression test at elevated temperatures
