EML is born

Dear Friends,
Let me assure you that we (the editorial team) are just as anxious as you are to see what kind of papers are published by EML, with similar anticipation as one looks at a new born baby for the first time.  Does the baby girl have big eyes like her mother? Or does the baby boy have little hair on his head like his father? Or the baby is just different, different from all other children, and beautifully so.

Optical microscope for three-dimensional surface displacement and shape measurements at the microscale

We report a novel optical microscope for full-field, noncontact measurements of three-dimensional (3D) surface deformation and topography at the microscale. The microscope system is based on a seamless integration of the diffraction-assisted image correlation (DAIC) method with fluorescent microscopy. We experimentally demonstrate the microscope’s capability for 3D measurements with submicrometer spatial resolution and subpixel measurement accuracy.

New Background of Micromechanics

Dear Colleagues,

One proposes a new background of micromechanics defining a new field of micromechanics called computational analytical micromechanics (CAM, see the abstract attached). It offers opportunities for a fundamental jump in multi-scale and multi-physics modeling of random heterogeneous media with drastically improved accuracy of local field estimations.  I would be happy if you pay your attention to CAM.

Dear ALL,

Which reading material/source that describes the good understanding of stress triaxiality?

What is the role of stress triaxiality for FE analyst?

I have read a lot of papers/articles but still have confusing me on the fundamental of stress triaxiality.


Practical Application of the Stochastic Finite Element Method

If you're interested in stochastic finite element analysis, you might like to know that we've just published a paper that reviews the "practical" application of the method. The paper first outlines the main methods of incorporating uncertainty into engineering computations. It then presents "practical" examples across a range of disciplines of where these methods have been used.

We hope that this paper is a good starting point for those looking to adopt stochastics in their work.

Two Postdoc positions in UCLA Soft Materials Research Lab

The Soft Materials Research Laboratory directed by Professor Qibing Pei in the Department of Materials Science and Engineering at University of California, Los Angeles is an interdisciplinary research group developing synthetic polymers and nanocomposites for advanced electronics, electromechanical, and photonic devices. Current research activities include but not limited to dielectric elastomers for muscle-like actuation, bistable electroactive polymers for large-strain rigid-to-rigid actuation, and stretchable electronics.

I am [still] confused about gradients, vectors, deformation gradient, etc.

I am creating this blog entry to have my confusions about gradients, vectors, and deformation gradient, etc., straightened out once (and hopefully for all time!) ... My confusions got exposed (even to me) while commenting on a thread started by Prof. Suo here [^]. In particular, I realized my confusions after writing this comment [^] there.

Chip formation in thermomechanical simulation of metal cutting


I am simulating thermomechanical model in Abaqus. I am not able to get chip out. I have used shear deformation criterion. Is there any key step to achieve this?

Also I am facing problem with coupled thermomechanical CPE4RT element. I am using Dynamic explicit thermal displacement step. In this step I didn't find adiabatic heating option, Abaqus is giving me warning about it. What are the necessary inputs for this simulation.

Please answer if anybody knows about this.

The attached notes are written for a course on plasticity.  When I update the notes, I will post a link on my twitter account:  

Rheology is the science of deformation.  This science poses a question for every material:  Given a history of stress, how do we predict the history of strain, or the other way around?

On the stress singularities generated by anisotropic eigenstrains and the hydrostatic stress due to annular inhomogeneities

The problems of singularity formation and hydrostatic stress created by an inhomogeneity with eigenstrain in an incompressible isotropic hyperelastic material are considered. For both a spherical ball and a cylindrical bar with a radially-symmetric distribution of finite possibly anisotropic eigenstrains, we show that the anisotropy of these eigenstrains at the center (the center of the sphere or the axis of the cylinder) controls the stress singularity.
