Recently I had lots of problem with linking ABAQUS and Fortran compiler together. I did all of the things which has been described in forums but none of them worked for me. Finally I found the solution.
I'm using ABAQUS 6.12-3, Visual Studio 2012 Professional and Intel Composer XE Suites 2013. For linking them simply follow these steps:
1- find the file ifortvars.bat and its path.

Learn about how Simpleware software was used to aid in the creation of models for analysing the risk of cerebral aneurysm rupture in ANSYS. The results have been used to develop a clearer sense of how image-based modelling can help to better diagnose aneurysm risks based on the mechanical properties of tissue.

In recent times, mechanical metamaterials and a phononic crystals have attracted the attention of some groups, as they allow to exploit on a larger scale phenomena known from solid state physics, such as the creation of band gaps at certain frequencies. The peculiarity of metamaterials is that their effective properties emerge from the periodic geometric organization of their unit cells rather than from the constituting bulk materials. Furthermore, metamaterials can be built in any size, ranging from the nanometer to the meter scale, and out of any material to suit different needs.
With the hope that this write-up will be useful to researchers, students, and industrialists interested in working with IGA. The 3D code including enrichment for fracture mechanics can be downloaded on SourceForge

Cardiff University's endowment funds have accumulated sufficiently to offer three PhD studentships to full time students.
Funding is available on the following basis:
1. Two x 3-year full-time PhD studentships where 50% of the costs (fees, standard stipend and project support) are met through the endowment fund and the remaining 50% will be match funded by the School.
The cost of the studentships has been estimated as follows:
- tuition fees for a full-time Home/EU student are currently £3,900 in 2013/14;
In the laminar mode interactions
among molecules generate friction between layers of water that slide with
respect to each other. This friction triggers the shear stress, which is
traditionally presumed to be linearly proportional to the velocity gradient.
The proportionality coefficient characterizes the viscosity of water. Remarkably,
the standard Navier-Stokes model surmises that materials never fail – the transition
to turbulence can only be triggered by some kinematic instability of the flow. This
premise is probably the reason why the Navier-Stokes theory fails to explain

hi every one
I want to find stress intensity factor in crack by j-integral in abacus?
how can I do this?
Applications are invited for few open positions in the area of
multiscale simulation of fatigue and fracture of advanced alloys and
nano-material based composites. Primary focus of this research is investigation
of fatigue and fracture behavior of nanomaterials and to develope various
constitutive models for continuum, based on large scale atomistic simulations.
Research effort will include development of analysis and design methods toward
improving material/structural behaviour using computer simulation. Interested
candidates should have preferably MTech/ME degree in
mechanical/civil/aerospace/material engineering discipline with good knowledge
Three-dimensional simulation of crack propagation in ferroelectric polycrystals: Effect of combined toughening mechanismsSubmitted by Amir Abdollahi on Fri, 2014-01-03 06:43.
We simulate the fracture processes of ferroelectric polycrystals in
three dimensions using a phase-field model. In this model, the grain
boundaries, cracks and ferroelectric domain walls are represented in a
diffuse way by three phase-fields. We thereby avoid the difficulty of
tracking the interfaces in three dimensions. The resulting model can
capture complex interactions between the crack and the polycrystalline
and ferroelectric domain microstructures. The simulation results show
the effect of the microstructures on the fracture response of the
material. Crack deflection, crack bridging, crack branching and
ferroelastic domain switching are observed to act as the main fracture
toughening mechanisms in ferroelectric polycrystals. Our fully 3-D

The velocity and instability of crack motion in 2D hexagonal lattice of graphene under pure opening loads
are investigated by atomistic molecular dynamics simulations. The brittle crack along zigzag direction
in a strip can propagate supersonically at even 8.82 km/s under uniform normal loading of edge
displacements. Crack moving straightly at low speeds produces atomically smooth edges, while kinking
occur beyond a critical speed around 8.20 km/s equivalent to 65% of Rayleigh-wave speed in graphene,
which validates previous theoretical predictions of rapid fracture instability in elastodynamics, and
rough and irregular edges with oscillatory overhangs are formed subsequently.

I am using Abaqus/CAE 6.10 to simulate a Debonding test (cohesive behavior for composite delamination).
I ran a Abaqus debonding simulation example (from Abaqus online documentation - Abaqus Benchmark Manual - 2.7.1 Delamination analysis of laminated composites).
The Abaqus/Explicit three-dimensional model with surface-based traction-separation behavior used a surface contact interaction property with:
- default Cohesive behavior
- XFEM-based LEFM (using VCCT) fracture criterion.
The following ERROR message appeared after submiting the job:
can i include mechanisms while creating DMIG in FEA?
I read with interest an excellent discussion about Linear Algebra in Mechanics. I am attaching Chapter I: Tensor Preliminaries from my book Elastoplasticity Theory, which includes Hill's analysis of induced tensors mentioned in the discussion.
