Y.Nishidate and G.P.Nikishkov. Curvature estimate for multilayer rolledup
nanostructures with cubic crystal anisotropy under initial strains. Journal of
Applied Physics, 105:093536–1–6, 2009. |
| The generalized plane strain solution for anisotropic multilayer nanostructures with cubic
crystal symmetry under the influence of initial strains has been derived. This solution
can be used to estimate equilibrium curvature radius and strains/stresses of rolled-up
anisotropic multilayer nanostructures, whose deformations are induced by crystal lattice
mismatch. The solution has been applied for calculation of curvature radii and strain
components of a bilayer In0.2Ga0.8As/GaAs rolled-up nanostructure. The results are
in agreement with those obtained by a finite element analysis. |

Conference on E-Learning in Corporate, Government, Healthcare, and Higher
Education (E-Learn 2009), page 64, Vancouver, Canada, 26–30 October 2009. |
| A simple course management tool (CMT) has been developed using Java and Web
technologies. The Java application runs on any computer and supports interaction
between an instructor, teaching assistants and students. It provides graphical user interface
and includes aWeb server, a mailer and a simple database. The HTTP protocol
is used for all communications. Both teachers and students employ Web browsers to
access the CMT server. Students have possibilities to check their personal data (scores
and comments), to download educational materials, to upload files and to communicate
to the instructor or teaching assistants. Main difference of the presented CMT
from available course management system is in simplicity of its learning, installation
and support. |

crack growth. In Second International Symposium on Computational Mechanics
(ISCM II), page 6 pp., Hong Kong – Macau, 30 November – 3 December
2009. |
| Modeling of stress corrosion cracking (SCC) is performed using the combination of the
finite element method and the symmetric Galerkin boundary element method. The
uncracked structural component is represented with finite elements. The crack is simulated
using the boundary element method. The superposition principle is employed
for combining two solutions. The equilibrium state for the system of the structural
component and the crack is reached after several iterations that alternate between
two methods. It is adopted that the crack develops in the direction of the J-integral
vector and the crack growth rate is determined by the mechanochemical model using
the effective stress intensity factor based on the J-integral value. Results of SCC crack
growth modeling are presented for inclined semi-elliptical surface cracks under tensile
loading |

G.P.Nikishkov. Programming Finite Elements in Java. Springer, London,
2010. |
| The book focuses on algorithms of the finite element method and their programming.
First, general equations of the finite element method for solving solid mechanics and
thermal conductivity problems are introduced. Then, algorithms of the finite element
method and their programming in Java are considered. In addition to solution methods,
the book presents algorithms and programming approaches for mesh generation and
visualization. |

processes, pages 151–165. ICTs for Modern Educational and Instructional
Advancement: New Approaches to Teaching. IGI Global, Hersley, USA, 2009. |
| A platform-independent Java Web application TSI that supports communication between
an instructor, teaching assistants and students in a traditional on-campus course
is presented. Using the TSI, the instructor and teaching assistants can handle most of the
routine work: upload student personal information, send students personal emails, etc.
The system can easily be installed and administered individually by an instructor inexperienced
in computers. Students can check their personal data (scores and comments),
download educational materials, etc. |
