I am modelling RCC with a VUMAT. The subroutine is ok with 3D solid, shell or 2D plane stress, but when I use 3D shell and include Rebar it doesn't run.


I can run it with reinforcement in Solid or plane stress element.


Can any one guide me where I am making the mistake.

Journal Club Theme of October 2014: Microbial fuel cells - When mechanics meets bioelectrochemistry

The aim of this Journal Club is to provide a forum for discussing the role of applied mechanics in bioelectrochemical systems such as microbial fuel cells, and the potential of computational mechanics during upscaling of those systems.

Hamilton's principle

I continue to receive inquiries about the monograph Hamilton's Principle in Continuum Mechanics, published in 1985 as Research Notes in Mathematics No. 139 by Pitman Publishing, Ltd. Now out of print, it is in the public domain and is attached here. My initial objective in writing it was to discuss the theoretical foundations of the applications of Hamilton's principle to mixtures that I had developed with D. S. Drumheller and others during the preceding decade.

MS 54: Multiscale Modeling and Simulation of Fracture and Fragmentation Processes

postdoctoral position - isogeometric analysis

IMATI-CNR and the Mathematics Department of the University of Pavia offer a postdoc position on isogeometric analysis. This research project focuses on the design and implementation of innovative isogeometric methods for solid/fluid mechanics.  In particular the target applications are related to

- nearly-incompressible and fibered materials

- fluids in geological formations

This research project is partially supported by the private sector, and is supervised by Annalisa Buffa and Giancarlo Sangalli.

SNP 2014 meeting

This 52th meeting of the Society of Natural Philosophy, entitled “Scale Bridging in Mathematical and Mechanical Sciences”, is focused on the formulation, analysis, and simulation of boundary-value and initial-boundary-value problems for partial-differential equations describing the behavior of materials which exhibit complexity and structure on varying length and time scales. Attention is specifically addressed to the mechanics of complex fluids and solids, including nano- and biomaterials.

Reminder: Call for Nominations for the Eshelby Mechanics Award for Young Faculty

It is my pleasure to solicit nominations for the "Eshelby Mechanics Award for Young Faculty". This award, launched in 2012, is given annually to rapidly emerging junior faculty who exemplify the creative use and development of mechanics. The intent of the award is to promote the field of mechanics, especially among young researchers. While interdisciplinary work that bridges mechanics with physics, chemistry, biology and other disciplines is encouraged, the ideal awardee will demonstrate clear inspiration from mechanics in his/her research.

ABAQUS Element Connectivity


I am trying to mesh the hollow sphere attachged using structured BRICK-8 elements. It turns out in order to have a structured mesh, I have to have 2 partitions such that four quadrants be generated.

What I only need from ABAQUS is the element connectivity. I do not need to solve any problem.

Stretchability and compliance of freestanding serpentine-shaped ribbons

High-performance stretchable electronics have to utilize high-quality inorganic electronic materials such as silicon, oxide or nitride dielectrics, and metals. These inorganic materials usually crack or yield at very small intrinsic strains, for example, 1%, whereas bio-integrated electronics are expected to at least match the stretchability of bio-tissues (20%) and deployable structure health monitoring networks are expected to expand from wafer scale (several centimeters) to cover macroscopic structures (several meters).

Mechanics of supercooled liquids

In a pure liquid, molecules touch one another but change neighbors frequently.  External forces cause the liquid to change shape by viscous flow.  Thermal agitation causes  molecules to undergo self-diffusion.  The two phenomena--viscous flow and self-diffusion--often result from a single rate-limiting process:  molecules change neighbors.  This simple picture is amply confirmed by the Stokes-Einstein relation, which links the viscosity and self-diffusivity for many liquids over wide ranges of temperature.

crack extension curve

Dear all

My project work is in crack analysis, so I used cohesive zone model for crack analysis in Abaqus.I implement the cohesive element in crack path but I don't known how to plot crack extension vs time(load, J-integral) curve.

Pls suggest the procedure for ploting crack extension curve.
