Journal Club Theme of September 2015: Kinematics of Crystal Elasto-Plasticity: F=FeFp
This month’s blog focuses on one of the most common kinematic assumptions in the continuum mechanics of finite elasto-plasticity: the multiplicative decomposition . This expression decomposes multiplicatively the deformation gradient of the body into to the elastic () and plastic () deformation tensors; and it will be discussed here in the context of dislocation mediated plastic deformations.

Ph.D. Position in Computational Mechanics
A fully-funded Ph.D. position is available with a start date of Spring 2016 or Fall 2016 at the Computational Biomechanics and Solid Mechanics Laboratory (http://www3.villanova.edu/biomech/) at Villanova University which is located in the greater Philadelphia area (http://www.villanova.edu).
SHPB testing: speed of plastic waves in short cylinders
Dear iMechanica community,
I came across a problem in plasticity for which I am unable to find a reference in the literature and kindly ask your advice.
Temperature as a solution dependent variable ???
Hi,
i am simulating a heat transfer in soil using umatht subroutine.need to specify the variation of the temp as a solution dependent variable??
Anyone have any idea how can i do that in abaqus/cae or is there anyway to do that by editing keyword(indirectly)?
eny help is realy appreciated,
Geostatic problem in Abaqus
Dear collegues,
I am doing consolidation problem for saturated 1 m clay layer with 6 m sand layer above.
ABAQUS is used.
The model of soil - Cam-Clay.
Initial stresses in the soil are given.
The initial pore pressure as well set.
A postdoc position in crystal resonator modelling and experiment
A postdoc position is available in the Department of Engineering Technology, University of North Texas-Denton in the fields of crystal resonator modeling and experiment. Candidates should have a PHD degree in engineering mechanics, mechanical engineering or electrical engineering and should have some experiences in the following:
(1) In-depth understanding of piezoelectric theory and crystal resonators,
(2) Proven publication record on crystal resonator modelling or experiment,
(3) Fundamental knowledge on tensor analysis and transformation,
Additive Manufacturing (3D printing) lab at TU Delft
After several years of research in the area of additive manufacturing, biofabrication, and additively manufactured biomaterials and implants, I finally put up the first version of the website of my lab. I will gradually improve the website, but there is already links to all publications coming out of my lab in the general area of AM.
How to contact between solid elements after cohesive elements failed?
Hi, I have used langrangian framwork proposed by Needleman in 1994 to model materials' failure under compression. In this model cohesive elements were inserted along solid elements boundary.
problem related to umat subroutine.
hi all,
i am working on abaqus and using umat subroutine.
after i wrote a simple example code(isotropic) on fortran language and make a model on abaqus, i tried to run it together. it is worked.
after, i changed the simple code to my own code(anisotropic code) and run it with abaqus. i
the result is following:
too many increment made for this increment.
for step 1 converge but not step2 step 3 step4.
I tried to reduce the time increment but not way even the mesh i changed.
the time step i used is dynamic implcit
