Fully Coupled Fluid-Structure Interaction Analysis of Wind Turbine Rotor Blades-2012

A fully coupled fluid-structure interaction analysis of a wind turbine rotor is
presented. Abaqus/Standard and STAR-CCM+ are directly coupled through the
SIMULIA co-simulation engine. With this approach, a high fidelity modeling
strategy can be used to develop an accurate understanding of the blade dynamics.

Simulation of the Ballistic Perforation of Aluminum Plates with Abaqus/Explicit -2012

Simulation of the Ballistic Perforation of Aluminum Plates describes Abaqus/Explicit modeling of the ballistic impact of metal projectiles
on metal targets. It will demonstrate the utility of Abaqus/Explicit as a tool
for reducing the amount of experimental testing as well as assessing the
projectile residual velocities and time-resolved kinematics.

Pipeline Rupture in Abaqus/Standard with Ductile Failure Initiation-2012

Pipeline Rupture in Abaqus/Standard will be used to predict the burst pressure of a steel pipe-line
with a notch-type defect. A ductile damage initiation criterion is used, and
favorable comparison with available experimental data will be shown.

Coupled Electromagnetic and Fluid-Structure Interaction Analysis of a Solenoid Valve-2012

It is a methodology for building a coupled electromagnetic and fluid-structure
interaction analysis of a solenoid valve. A seamless integration between the
applicable analysis techniques allows for the simulation of the complex
multiphysics interactions.

PhD Positions in Fluid-Structure Interaction

PhD positions are available in the Department of Mechanical Engineering at the University of New Orleans, starting in the spring 2013. Applicants with strong background in the areas of solid mechanics, composite structures, finite element analysis, and fluid-structure interaction (using Abaqus or ANSYS) are encouraged to apply. The research projects are on small-scale unmanned aerial systems. Applicants can learn more about the PhD program from the website, http://coe.uno.edu/coe_web/graduate/phd.htm.

Finite Element Analysis of the Indentation-Induced Delamination of Bi-Layer Structures

Delivered by Ingenta to:
University of Southern California
IP : 132.174.255.3
Sun, 29 Jul 2012 00:05:58
Contact deformation can cause local damage of mechanical structures and lead to structural failure
of mechanical devices. In this work, we use the finite element method to analyze the indentation-
induced delamination of a film-substrate structure and the critical tensile stress as the criterion to
determine local delamination on the interface between the film and the substrate. The simulation

Finite element analysis of the spherical indentation of transversely isotropic piezoelectric materials

Finite element analysis was used to analyze the indentation deformation of
a transversely isotropic piezoelectric material (PZT-4) by a rigid spherical
indenter. Three cases were considered in the analysis, which included (a)
the indentation by an insulating indenter, (b) the indentation by a conducting
indenter and (c) the indentation of the piezoelectric material with equal electric
potential on the top surface. The indentation load was found to be proportional
to the 3/2 power of the indentation depth for all three cases. Using the simulation

Orthotropy in Plasticity and Creep using ANSYS

iMechanica,

Using the ANSYS software, have any of you had any success with assigning distinct Hill's plasticity and Hill's creep constants to the same material?

Best Regards,

activate and deactivate the element

Anyone experience in the activate and deactivate element automatically
in ABAQUS. got any suggestion how to do it or example can refer?
Ex: when element 1 exceed the maximum strain, i need to activate the element 1. and
when element 2 less than minimum strain, i need to activate the elements surrounding element 2.
my purpose activate and deactivate the element is to get the equilibrium of the model after some steps.

the attachment above is the example model that what i means.
thank you.

Objective Stress Rates in Finite Strain of Inelastic Solid and Their Energy Consistency

In many practical problems of solid mechanics, it is sufficient to characterize material deformation by the small (or linearized) strain tensor. But there are also many problems where the finiteness of strain must be taken into account.

MIT Postdoctoral Position in Finite Element Analysis for DNA nanotechnology

The Laboratory for Computational Biology and Biophysics at MIT (http://lcbb.mit.edu/) is seeking a highly motivated recent PhD graduate with expertise in nonlinear finite element analysis, ideally in the area of beam theory, with a keen interest in applying this knowledge to molecular modeling of DNA-based nanostructures. The candidate must have excellent communication skills, written and verbal, PhD-level training in finite element analysis, and a strong record of productivity publishing in high quality archival journals.

what is the best computer language to program finite element methods with?

Choose a channel featured in the header of iMechanica: 

hello.

I hope it is ok to ask this here. If not, please let me know which forum to use.

what do you recommned to use for programming finite element methods these days?

I am now learning FEM, and would like to start programming small programs to solve very simple problems to help me learn it better.

 I'd like to be able to plot easily (I learn better by seeing plots than just numbers). A friend recommeneded I use Mathematica or Matlab.  What other options do you recommend?

 This is the list I made so far:
