LOOP ERROR IN MATLAB

Submitted by Zuhaib Nazir on

Dear Researchers

 

Can you please make a correction in my Code of MATLAB

X1=[1,2,3,4]';

X2=[5,6,7,8]';

U1=[9,10,11,12]';

U2=[13,14,15,16]';

for i=1:1:4

EPS1(i,1)= U1(i,1)/X1(i,1);

EPS2(i,1)= U2(i,1)/X2(i,1);

EPS12(i,1)= 0.5*((U1(i,1)/X2(i,1))+(U2(i,1)/X1(i,1)));

defG(i)=[1+U1(i,1)/X1(i,1) 0+U1(i,1)/X2(i,1); 0+U2(i,1)/X1(i,1) 1+U2(i,1)/X2(i,1)];

end

EPS11

EPS22

EPS12

are right but for defoarmation gradient  i am getting error of 

 

Nanosculpt: A methodology for generating complex realistic configurations for atomistic simulations

Submitted by Arun Prakash on

Atomistic simulations have now become commonplace in the study of the deformation and failure of materials. Increase in computing power in recent years has made large-scale simulations with billions, or even trillions, of atoms a possibility. Nevertheless, most simulations to-date, are still performed with quasi-2D geometries or rather simplistic 3D setups. Although controlled studies on such well-defined structures are often required to obtain quantitative information from atomistic simulations, for qualitative studies focusing on e.g. the identification of mechanisms, researchers would greatly benefit from a methodology that helps realize more realistic configurations. The ideal scenario would be a one-on-one reconstruction of experimentally observed structures. NanoSCULPT allows you to do precisely this for both crystalline and amorphous structures.

I am currently looking to fill an open PhD position in a project titled:

Advanced Virtual Design of 3D Printed Fusion Reactor Components

This is to continue recent work that uses X-ray tomography, high performance computing and finite element analysis to design the plasma facing wall of the ITER reactor. Recent related publications can be found below:

Quantification of GNDs in DP steels (with three developed criteria)

Submitted by Ali Ramazani on

The current work aims to predict the work-hardening behavior of dual-phase (DP) steel, focusing on the effect of transformation-induced geometrically necessary dislocations (GNDs). Equiaxed and banded microstructures were produced through suitable heat treatment cycles in a laboratory. Electron backscatter diffraction measurements were performed to characterize GNDs. The flow behavior was modeled within the micro-scale finite element method, considering the effect of the microstructures using the representative volume element (RVE) approach.

A Geometric Theory of Nonlinear Morphoelastic Shells

Submitted by arash_yavari on

We formulate a geometric theory of nonlinear morphoelastic shells that can model the time evolution of residual stresses induced by bulk growth. We consider a thin body and idealize it by a representative orientable surface. In this geometric theory, bulk growth is modeled using an evolving referential configuration for the shell (material manifold). We consider the evolution of both the first and second fundamental forms in the material manifold by considering them as dynamical variables in the variational problem.
