The proof of
Saint-Venant's Principle for curved bars is discussed and the formulation of
Modified Saint-Venant's Principle of the problem is established. The study
shows that Saint-Venant's decay of stresses is valid only for the curved bars
which are “effectively infinite”. It is essential and significant to develop

A new post-doctoral position is open for conducting cross-disciplinary basic research in the theory of heterogeneous structural materials. Candidates are sought with strong background in statistics or statistical mechanics, probability theory, and mechanics. A Ph.D. in Mathematics, Physics, or Engineering might be appropriate.

A postdoctoral position is available immediately at the Department of Biomedical Engineering, Johns Hopkins University for work on a project simulating cardiac mechanics in normal and failing hearts. A PhD in Mechanical or Biomedical Engineering or related field is required. The candidate is required to have strong expertise in modeling soft tissue mechanics. The  successful candidate is expected to be able to develop code to simulate the contraction of the heart as well as to conduct simulation research on abnormalities in cardiac contraction. Send inquiries to Dr. N.

The objective of this paper is to examine the instability characteristics of both a bulk FCC crystal  and a (100) surface of an FCC crystal under uniaxial stretching along a <100> direction using an atomistic-based nonlocal instability criterion.  By comparison to benchmark atomistic simulations, we demonstrate that for both the FCC bulk and (100) surface, about 5000-10000 atoms are required in order to obtain an accurate converged value for the instability strain and a converged instability mode.  The instability modes are fundamentally different at the surface as comp

Abstract

Recent advance in adaptive remeshing techniques now gives the possibility to efficiently simulate complex 3D crack growth using conform meshing of the discontinuity. An exemple of such kind of mixed mode simulation with adpative remeshing can be seen on YouTube:
