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

Hi

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.

RHEOLOGICAL MODELS

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

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.

Geometric nonlinear thermoelasticity and the time evolution of thermal stresses

In this paper we formulate a geometric theory of nonlinear thermoelasticity that can be used to calculate the time evolution of the temperature and thermal stress fields in a nonlinear elastic body. In particular, this formulation can be used to calculate residual thermal stresses. In this theory the material manifold (natural stress-free configuration of the body) is a Riemannian manifold with a temperature-dependent metric. Evolution of the geometry of the material manifold is governed by a generalized heat equation.

Elastic leak of a seal

Our paper in the new journal Extreme Mechanics Letter has come online:  An elastomeric seal may leak by elastic deformation without any material damage. We describe elastic leak using a theoretical model, and watch a seal deform and leak using a transparent experimental setup. The elastomer seals the fluid by forming contact with surrounding hard materials. As the fluid pressure increases, the contact stress also increases but not as much.

Fiber-reinforced tough hydrogels

Our paper has appeared in EML (Extreme Mechanics Letters) and can be downloaded.  Using strong fibers to reinforce a hydrogel is highly desirable but difficult. Such a composite would combine the attributes of a solid that provides strength and a liquid that transports matter. Most hydrogels, however, are brittle, allowing the fibers to cut through the hydrogel when the composite is loaded. Here we circumvent this problem by using a recently developed tough hydrogel.
